[Q] Why can I only use VOIP on some wifi networks? - Nexus S Q&A, Help & Troubleshooting

I set up my Gizmo5 account for SIP calling yesterday on the wireless network provided by my Verizon Fivespot, and it worked fine. Now I'm on my home network (Verizon DSL), and when I try to use Gizmo5 on my Nexus S, I get the error "Account registration failed: (transaction terminated); will try later." Why does this happen on only my home network? Is there anything I can do to get Gizmo5 to work at home?
Device: Nexus S
OS: Gingerbread 2.3.1
Carrier: None (Verizon Fivespot)

It may be network related at your house. Possibly a router/firewall not allowing the traffic in/out. I doubt it but I suppose the provider could be blocking that type of traffic as well.

What can I do to fix it though? I already checked my router settings and the firewall isn't blocking anything.

It isn't only the outgoing ports that need to be open (they definitely do), but the firewall has to support NAT *correctly*. SIP requires intelligence from a firewall, opening/keeping-track of outgoing/incoming UDP ports, etc. If your router supports it, try a third-party firmware like Tomato.

I had this same problem with new ubee modem/router. It is indeed NAT, and the ubee has no option to disable it.
I ended up putting my old router on the ubee DMZ and now gizmo and sipgate work.
Anyone have suggestions on making a ubee work with voip?

OpenDNS blocking gmail while using wifi tether for root users?

Are you using Wifi or 3G/Edge? Looks like the problem is with the admin that setup your Wifi.
Well sounds like you are using their DNS servers and someone blocked gmail.
go to opendns.com while tethering to change your settings if you can. You should see a "dashboard" link at the top right of the page.
OpenDNS is an alternative DNS service (normally DNS is provided by the ISP). Wifi-Tether-For-Root by default has OpenDNS hardcoded in as the default DNS (instead of T-Mo's DNS servers). Since all traffic on T-Mo 3G is routed through their central server, regardless of where you are physically, your ip on the internet will appear as coming from a T-Mo data center in Missouri or Kansas or something. Perhaps someone has maliciously set up an OpenDNS account with this ip and locked out gmail.
Edit: I am having no problems getting to gmail using WT4R. My tmo ip was different from the usual though. Perhaps they are load-balancing their US network. Last time I checked, my tmo ip came out in Kansas. This time however, it came out of Rhode Island. Strange, considering I am physically in California.
Could you lookup your internet-side ip address while tethering and see which tmo datacenter you appear to be coming from when your gmail access is restricted?
This is the first time I've ever used wifi tether. Was kinda wierd to see gmail was blocked. Working on setting up an opendns acct now.
Ok....I'm totally lost now. I've got an opendns acct setup. I'm lookin at the dashboard thing, and have no idea what to change to fix this issue?
You are going to want to go here https://www.opendns.com/dashboard/settings/
It should show your current IP in the drop down.
Turn off the filtering and make sure nothing down below is added.

Easy enough to figure out my ip addy....but no idea how to do the rest.
Weird thing though...I signed up fro an opendns acct, browsed around a bit in the dashboard and now gmail works? ~edit~ nvermind, spoke too soon...gmail is blocked again.
For some reason I have a problem wrapping my brain around this kinda stuff.
your ip could have changed

I see my IP under the network tab. Under the settings tab it says "to control your settings, you need to add a network to your account." If I click "add a network" it takes me back to the network tab where my ip is displayed. If I click add network, it says network already exists?
Bleh....
Like i said, T-Mo is likely load balancing across their many gateways. My guess is whoever locked gmail out only did it to one of the gateways. Your best bet is to change the DNS servers away from opendns.

The reason is because only one openvpn account can control a network. Whoever has messed up that tmo gateway has full control of it until that person or openvpn changes the situation.

It might be enough to edit /data/data/android.tether/conf/dnsmasq.conf with a text editor and substitute out the DNS values in there with your own DNS. I'll try it out later.

"wifi tether" should update the dnsmasq.conf-file automatically (will take the dns from your 2G/3G-connection) - this was introduced in version 0.95.
Type ... "getprop net.dns1" into terminal ... that should exactly be the nameserver in dnsmasq.conf (after you have started tethering).
Bleh....I need a break from phone tweaking for a bit. Buuurn ouuuut
Works for me
I just got home, tethered just to see if it would affect me too. Not problems at all.

harry_m is right. When I tethered to my G1 via WT4R (ver 0.9.6) and visited opendns.com, it showed the "Start using OpenDNS" button, indicating my currently used DNS was not OpenDNS. I verified that WT4R had fetched the G1's internal DNS setting by checking the dnsmasq.conf:
Code:
$ su
# cat /data/data/android.tether/conf/dnsmasq.conf
no-resolv
no-poll
server=10.177.0.34
server=10.176.80.242
I suggest you reinstall WT4R and choose no when it gives you the option to import old settings. This way, it will build your configuration files from scratch (and not use OpenDNS).

Sudden Network connection problem

Suddenly, I cannot to access functions that require connection to a network.
For example, Bing will not update categories or collections.
Windows update will not connect to the network.
It suggested I check my time and date? ...which are correct.
I can access internet, send and receive email and sms, check and update weather.
Just many things that require network connections do not work.
I'm not sure when this started. I don't remember changing any network settings.
I use T-Mobile in USA
Any ideas what i am missing?

Are you using a proxy?
Are you on the t-zones package? Maybe they are now blocking https (or SSL)?
DJG,
Good questions. When I first got my TP and put sim in, it did automatic setup to T-Mobile settings. I am on unlimited data plan. When checking settings recently, I noticed the APN was set to the WAP.voicestream.com, instead of internet2.voicestream.com. I changed that. I also noticed that This network uses a proxy server was checked, with no proxy name in the box. I tried checking then unchecking this and using it. No difference. Then I tried checking it and adding getmorespeed.voicestream.com. It seems like web browsing is a bit faster (maybe), but this didn't fix the other network access problems.
Could this be a T-Mobile problem, or a problem with my account at T-Mobile?
Do they need to reset anything?

[Q] Is Hide my Ass blocked by AT&T?

I'm trying to set up Hide my Ass VPN in my rooted Captivate but I can't get an Internet connection. Has anybody managed to set up HMA in a Captivate? If so, are there any special settings?
PS. Support told me that "Most providers block ports, use some proxies etc. which prevents VPN over 3G connections". How can I undo this?
I am no expert on VPN but if the ports services are being blocked on the ISP/3g/ect side there is nothing you can do just like some home ISP's that actively block servers on the home class connections the only way to get around it is pay for the plan that doesn't block those services/ports which is probably the VERY expensive enterprise package.
i dont know anything about HMA, but any other VPN option requires tun.ko module support in the kernel in order for it to work.
Thanks, I'll look into that.

Use dyndns.org unless my ISP just doesn't block the ports needed (which wouldn't surprise me, they do have the telnet port open on an internal router) but I've setup a VPN very easily using them. I just had PPTP encryption, not sure how something like L2TP would work across it or not.

[Q] Wifi autoproxy

ok, i've been looking for an app for a while now, and have not found anything thats close to what i need.
my business has two wifi networks.
one for employees and one for customers.
the problem is, when i need to test something on the customer wifi, (and any others) is that the proxy settings are a global setting, not a wifi specific setting.
is there an app that changes that for you when it picks up a different network?
(say, swaps the proxy settings to nothing when a specific saved network is found, and changes it to defined settings when another saved one is connected to)
would be amazing if there was, and it did not need root access.
in ICS(Android 4.0) you can set proxy for each wifi network
Use proxydroid (free) from Google Play Store... You can create profiles for each wi-fi network and bind these profiles to the wi-fi network so it starts automatically when you are connected to the wi-fi network. You need to be rooted for proxydroid to work.

still sets a global proxy, just makes it look like its wifi-specific.
Try Autoproxy, the name says it all. Also on the market.

[Q] Using the phone as a modem

Is there a way to use the Samsung Galaxy S III as a modem without using the USB Tethering option, but setting up a new connection through a modem in windows. If it is possible what should be the settings for the connection such as the dialing number and the modem initialization string?
Thank you.
Are you trying to use your Galaxy S 3 as a dial-up modem? just trying to clarify if this is what you are asking, I don't know if it's possible. Can I ask why you would want this?

Yes I want to use the phone as a dial-up modem. I want to connect it to a dd-wrt router as a usb device so that the router can use it as an external dial up modem to give access to the internet for a home network. (for both wired and wireless devices)
Humm I don't think it is possible my guess is your having unlimited voice and thinking that if I dial out that is all that will be used. Well your idea would need some sort of virtual dial up modem on the phone which it doesn't have. An app would need to be created just to do this also you would still need dialup ISP service. If I was you I would look into other options like NetZero 4g hotspot.

It has absolutely nothing to do with the unlimited voice. It still would work as data connection. Like for any other provider all you need is the correct number to dial (for example for T-Mobile it is #99*) and the proper access point name (for example for T-Mobile it could be internet2.voicestream.com). May be I did not state is clearly I want to use it as a 3g/4g dial-up modem, not a simple over voice dial-up modem.
Now the hotspot would not work. I need a unified connection for both wired and wireless devices. If I use a hotspot device than the wireless clients and the router would have to be connected to the hotspot network wirelessly and the wired clients would still be connected to the router which would make it two different networks. More over if the hotspot would to be removed than the whole system would have to be set up again.
