Since I can't reply in the BubbleUPnP dev thread because I'm a noob, I'll hopefully get an answer in this thread.
bubbleguuum, are you out there?
I LOVE BubbleUPnP, fantastic app. Everything works great except for accessing my media server through VPN with my Acer A500 (Honeycomb 3.1). I know my VPN is setup correctly because I can access my server remotely using a file explorer app. The DLNA server just doesn't show up in the BubbleUPnP server list, where as it does just fine when I'm at home on my local WiFi network.
I suppose it's possible that my DLNA server software (Serviio) is the problem, but it seems more likely an issue with BubbleUPnP.
I did a little research and it looks like there's an issue with VPN and "discovery through multicast". It looks like the only easy way around is to manually enter in server IP. Maybe this feature could be added to BubbleUPnP?

Same problem here. btw There is an option to manually enter the servers ip. Does not work through VPN here.
I have a doubt...
In one hand, you need to supply the public IP adress for bbubbleupnpserver to work...but in other hand you hide this adress behind VPN...Then how could this work ?
I'm using my transformer at school and the school is providing wifi to its students. But there are apparently some odd restrictions associated with it. No app of mine is allowed to access the internet with the exception of browsers and also I'm not allowed to download anything (it just says "download unsuccesful" no matter what I download or from where). I've tried to look for a reson for this and I found out that it might be some firewall settings on the computer that is hosting the wifi, I also asked the school's IT guy and he said that it's likely to be the reason. But the thing is that all the people with computers and iPhones can use applications that use the internet with no problems at all. This makes me think that the wifi host regards me as dangerous or suspicious for some reason, and because it does allow computers and iPhones to use apps that access the internet and are allowed to download files, I think that it might be fixable. Perhaps there are some particular settings that make the wifi host's security to regard me as dangerous and doesn't allow my apps to go to the internet. So what do I have to do for my apps to be able to access the internet and to be able to download files? I really want to know this, because many of the useful apps require internet and by not using them I'm not taking the full advantage of the device. I should also mention that my tablet is running 3.2.1.
But have you tried asking them about letting you use your "netbook" on their netbook. What's the worst they can do? say NO TABLETS ALLOWED? Because unless they know your exact MAC address, they probably won't be able to do anything about it. In my old school, I brought up that I would like to connect my windows mobile device to their network (when I was using it as an mp3 player) and they said sure (they had terrible firewalls which blocked most every site that was fun). Sometimes, the best kind of hackery is the social kind.

I guess his telling you to ask for permission to use your netbook on their network.
Well first of all I'm using a tablet running android 3.2.1. And I'm kind of confused by your use of the word network, because I said that I can use the school's wifi network for students, but only to some extent, meaning that none of my apps with the exception of the browser are not allowed to access the internet e. g. android market, google translate don't work, they just say that they are unable to connect to the network or something similar. Also downloading any file from anywhere is not allowed, it says download unsuccessful. But iPhone user's apps work perfectly fine. From this I concluded that there must be something about my tablet that makes their security think my apps are dangerous and therefore blocks them, and that because there is no such problem on iOS, I thought that the might be something wrong with my end, and that it it fixable. And my question was what do I need to do to fiz this? I hope that clarifies my point.

yes, thanks, I was kinda in a hurry when I typed that
Ask your school's IT department. Network configurations can be quite complex, and without knowledge of how or what they're blocking- it's hard for us to help. IT would know the issue better, or at least give the explanation as to why it isn't working. For instance, last year at my college nothing but computers were allowed to connect to the wifi. Such control can be done on the network side, and it may not be your tablet's fault.
Have you any friends with an Android device, or better yet android tablet?
I did ask the IT guy and he said that he has no control over the security settings, because it's a network across all of the schools in the city, not just the school in which I am.
Hey, I've tried using dropbox at school and then it says "cache access denied", maybe that can somehow clarify my problem.

Have you set your settings/applications to allow unknown sources (ie is it ticked).

That's only to allow installing apps not from the Market (sideloading). It has nothing to do with an app working or not.
Haven't you ever heard of proxy and content filtering?
Schools often set up proxies to restrict certain sites and content from working on their networks. They do it for a variety of reason, including bandwidth conservation, content filtering, network security, etc.
More than likely, they have blocked anything that they deem unnecessary. That means that probably only port 80 is allowed (the http port), possibly a few others for https, pop3 and imap for email, etc.
However, if you're a more advanced user, you can probably bypass right past all of this stuff by setting up your own proxy, or using encapsulation (like nstx or icmptx) to bypass their proxy by encapsulating other services inside DNS or ICMP traffic which are usually allowed to bypass the proxy at school. Like I said though, these are advanced techniques and require you to research and set it up yourself.

No, I do not no anything about proxy or content filtering, but I remember when I was connecting to the wifi network of the school I was asked to configure the proxy settings by putting some ip address ( I presume that it is an ip adress because it looked like one) and writing 8080 in the port field. If I didn't configure it like that, the internet would simply not work. Could you please tell me where I could educate myself about bypassing proxies or is i a matter that would require a very long time to learn and a lot of prerequisite knowledge?
And by the way, are you sure that this could be done on a tablet? All of that fiddling around seems to require a considerable degree of control which android may lack, or would rooting give me that control?

OK yeah you are going through a proxy then. The good news is, that because you have to configure it manually, they probably aren't using transparent proxy which can make it easier to bypass.
Getting nstx or icmptx working natively on Android should be possible in theory as both are lightweight and designed to work in Linux... perhaps it can be made into a module that can be activated/deactivated with a shell script, or added to a custom kernel.. obviously this would require a rooted tablet to accomplish.
The other required part of the equation is a computer accessible from the internet, which you can set up install a DNS server and nstx on.
If you manage to get it all working correctly, set your home IP address as your proxy instead of your schools proxy, and you should be able to get through. It should also work to let you access the web for free at places like Starbucks or at hotels where the web is normally routed to a site where you have to pay for web access.
Good luck!

That sounds awesome maybe you could make the app id buy it
I found two apps on the android market : proxydroid and ssh tunnel, do you think they would help me to bypass the school's proxy?
And by the way, how legal is this business? I mean I doubt that the school would send be to jail for using google translate but I'm still curious.
Legal issues are a potential problem, but its doubtful it would ever be a problem at school. Setting this up on your tablet certainly isn't illegal in itself, but if you're stealing wifi that you would otherwise have to pay for, you CAN get yourself in quite a bit of trouble if you get caught.

Ok thanks, wifi network in the school is free for all students so I should be ok. But what about those apps I mentioned before?
And how would I protect myself from geting caught and what is the likelyhood of me getting caught? Can they immediately notice it if someone's trying to bypass their firewall or not? I should point out that the it manager in our school knows quite little about the sexurity system or ao he told me when I asked him whether my problem is somehow connected to their security settings, but the network is not pwned by the school, it's owned by the city and it is present in many schools beside mine, so I think that they might take their security seriously. So basically what I am trying to say is that if I investigate this matter, come there and bypass the proxy so that the youtube app works, is it likely that I am going to get caught, and if yes then what are the ways of minimising the risk (please bear in mind that I have not experience in this)? I'm asking this because I think it's not a very good idea to just walk in and hack the network without any experience and expect that there is no possibility of getting caught.
No neither of those apps are really the solution to your problem. There isn't currently an app for Android that will set up encapsulation like I'm talking about.
And yes, your IT manager at school "might" be able to catch you, but only if he's specifically looking for it. What this basically does is encapsulate your regular IP traffic inside DNS packets (or pings for the icmptx method), which are generally allowed to pass through firewalls and content filters. Basically, it is detectable if your network administrator is looking in the right place and knows his stuff. There would either look like a constant stream of DNS requests from a particular IP on the school network, or a constrant stream of ICMP traffic (pings) being sent out. However both ICMP and DNS are normal for any network, so its also equally possible that the administrator never notices that anything is wrong at all...
Some more sophisticated networks may employ transparent DNS or transparent proxy, which would make these efforts much harder. Transparent proxy is able to intercept any traffic and force it through the proxy at school, while transparent DNS is able to intercept DNS traffic and force it to use a specific DNS server regardless of settings on your tablet.
Like I said in the beginning though, these are really advanced networking tricks that certainly aren't easy to set up, even when all the components are readily available.. its possible they haven't even been attempted yet on an Android device. That said, it shouldn't be difficult to port either icmptx or nstx over to Android for somebody with the requisite programming skills.
I am hoping someone can help me, since I am having a problem. The problem is that I am bored with the current "regular" section of apps on the market. I want to find something that is useful (even revolutionary!) but I cant find anything. I dont care about games, photo editing apps, music apps, "juice savers", or any of the other crap available on the market. I am looking for a really cool developer type app that typical users dont care about. My phone is rooted so basically the sky is the limit. Does anyone have any suggestions for me??
Hmmm.. maybe make your own I'll test out for you.. I'm is same boat bored with all the apps. I have all the required software to make apps just not sure where to begin..
I wouldnt be opposed to writing my own, but I am looking for inspiration first. Thats why I want to see some of the innovative apps out there. The problem is there is nothing particularly exciting, from what I can find at least. I am sure there are people who have developed something cool I just need to find it!
Im currently doing some learning ARM/x86 assembly for embedded stuff. Im also currently working with the android kernel. Sometimes i like to sit with my phone instead of a laptop here is a list of apps and stuff i use on the phone to make things go smooth.
(market) droidedit pro - this is the best easiest code editor ive used so far, its light it supports a ton of languages and has sftp and ssh command support. The ssh makes it easy to build stuff on your main remote machine.
(market)x-plore - pretty sweet file manager. it is a double tree view that can connect to the lan ftp and picassa. It also has total root access. I can basically work with any files even on typically read only directorys.
(market)ideterminal - basically the android sdk on your phone along with java compilers and ton of command line goodies.
Add a debian chroot to your phone this opens up so many possibilitys like to vnc into an x server on the phone and compile natively without the hassle of small screen no keyboard.
ssh combined with dropbox is also your friend.

I also mess around with embedded ARM devices for fun. My current project is FreePBX (Asterisk VoIP system) that I installed on a SheevaPlug "plug computer". At the moment I am trying to figure out the best way for me to incorporate my Android devices with that platform. The two apps I like am currently using a lot are:
1) FING. Its basically a network analyzing program that tells you about all devices attached to a network. If you are familiar with the older PC program called [email protected] this is essentially the Android version of that.
2) ConnectBot. A fairly straight forward SSH/Telnet client with a few extras.
I am really on the lookout for these kinds of apps. If you can think of others that might be interesting I would love to know. We have someone similar interests so I am curious what else you like.
If you are at all interested in my PlugPBX deployment you can check it out at the following thread.

I actually had downloaded fing but it wont work on my phone i have no idea what the deal is when i from command line or any program need to ping i get an error like ICMP operation failed, i dont have a problem with any networking software i.e ssh, VNC, remote web desktop (this is a cool toy, makes sms on pc simple also).
Oh ya there is also a dynamic DNS app to so you can use something like no-ip.com and to get a static host name for your phone, for free. Like mike.no-ip.com would connect you to your phone from anywhere, the client program on the phone updates the DNS server that provides your dynamic DNS name. I guess the app is generic and works with most if not all dynamic dns hosts!
Im not really into voip, i just havent ever done anything with it. although i only have 300 minutes and unlimited data so voip may be a good idea, i just dont know any free service.

Which DYDNS app are you using? I have tried a few and none work. Which carrier do you have?
there are many apps being added to the market everday.. u might want to explore them keenly..
As you all know most US (and i believe other) carriers try to charge us more for the data we already pay for if we want to use it in any method besides from our phone. There are a lot of apps that claim to get around it and it works for some and not for others, after some extensive google-fu and research i have found out that most if not all carriers use one of two methods of detecting tethering. 1.if the built in tethering is used the phone will use a separate tether specific apn 2.they look at the TTL of a packet, if tethering is being used the TTL will last past the WAN of the phone.
So i set out to try and find a way around this and a method of tethering that would work safely for all and get around TTL detection and i believe i have now found it.
Things you will need:
-Root
-ConnectBot
-ProxyDroid
-PDAnet (or any other tethering app)
-Something to SSH into
I will post more detailed instructions with screenshots and such if anyone wants but for now ill just keep it simple. Make sure your phone is on 3/4G. Open ConnectBot and connect to your ssh server, bring up the options menu and select port forwarding. Setup a dynamic (socks) proxy on port 8080 (or w/e you feel like) now open proxydroid and set host to 127.0.0.1 and make sure to enable global proxy (this does not work on all phones if it does not work for you then there is not much you can do) now open up a browser and go to any of the various ip checking sites and make sure your ip is showing up as the ssh servers ip and not a mobile one. Now enable pda net and do the same from the tethered device. If the ip is showing up as the remote servers then congratulations you are now tethering and they cant see the packets going to anything but the phone because everything is contained within the SSH session. Meaning the TTL on packets will end at the phones WAN as they expect them to.
I have been doing this on AT&T for some time now (around a month) and so far they have not found out and all is well, hope this helps at least a few people good luck!

I tried following you instructions, but when I try to visit a website no connection is available. What ssh server are you using. Have any idea where I may have gone wrong?

Has anyone been able to get this working. Whenever I select "Global Proxy" in ProxyDroid, I get no data. I changed the host to 127.0.0.1, but should I leave the port to default 3128 and Proxy Type to HTTP? Is there any other changes I should make in ProxyDroid? Thanks

Make sure you set the user agent on your computer browser to mobile. Had to do tethering for a client few days ago, and that was the problem. For Firefox and Chrome there are plugins for it.
Thanks for your response....I haven't gotten to the PC as yet. I am don't get any internet connection when I enabled ProxyDroid in with Global Proxy checked. And the OP said to make sure it is selected. So this is where I am stuck. Not sure whether I need to do any other configuration in regards to ProxyDroid. But thanks for your help.
Is it possible to setup an ad blocker as part of my personal vpn server? I'm unsure of exactly how ad blocker vpns work (such as ad block plus/blokada), but I'm a little hesitant/untrusting of having this vpn connection always on and running all of my traffic through it.
What would I need to do set this up myself? Alternatively, maybe someone could explain what exactly I'm exposing by having [blokada] enabled all of the time?

I'm kinda confused by your question in the first part. On what hardware do you intend to do the blocking? on your android device or on a remote/local server? if you intend to do that on android, then here are some things to consider:
There is the Root method, which I assume based on your question you don't want.
Then there is the rootless method, which is basically an exploit of a loophole in how android handles VPNs. Apps like Blokada and such supposedly establish a VPS locally and block DNS blacklisted requests by leveraging the VPN permission. you can use different apps to monitor them and see what goes out, but you most likely won't find anything suspect.
If you're that paranoid, I suggest using the web server feature in the Adaway app, which lets you use your own host list/DNS block list, sign it yourself for your phone to Trust (as trusted agent or CA certificate) and apply. Ofc doing it with adaway takes away (literally) the convenience of a self updated list, so you have to find your own lists and update it regularly for maximum block-ness.

Thank you, that is super helpful information on how ad blockers work on non-rooted devices. I am not rooted (after Google started automatically updating Pixels I decided the hassle of manually flashing updates and the loss of Android Pay (at the time) wasn't worth it).
I have a Wireguard VPN server on a FreeNAS server at my house. I'm not sure what blokada can track and/or conceivably redirect my traffic using their own DNS server (?). If I can set up a "VPS" and DNS blocking using publicly available lists through my own VPN or a FreeNAS jail/port or my router, I'd prefer to do that.
Maybe I'm overthinking this though haha...

I can relate heavily on the google pay front, but I'm a power user through and through. not having total control freaks me out so root is a must for me, so i gave up using it.
Regarding the host/adblock setup, i do think you're overthinking it. A router with openwrt is basically 80% already pre-configured with dnscrypt and the tools necessary. Using FreeNAS jail, there are sooooo many tuts online for that, i won't even need to tell you how myself. Personally, I use a PI-hole in my home and wireguard/cha cha20 protocol on my router, the webserver feature from adaway on my phone and haven't seen an ad in almost 2 years now.
