DNS Configuration For FTP (Public Seems Blocked?) Help Please! - General Questions and Answers

I have had Serv-U and No-IP setup for the last couple of years without issues, but I recently upgraded to the new Clear (Clearwire) modem which seems to be blocking outside access.
Windows is configured, internet works, printer sharing works, internal sharing, etc. I can ping out, I can access my FTP server when I choose the local IP - but when I ping my external IP or try to put it in the browser it won't work.
I have forwarding setup, even bypassed my router but still I can't seem to gain access. I have included several photos, I believe there's an issue in my DNS or IP settings, I'm just unfamiliar with this router and my knowledge on IP shaping only goes so far.
I have an HTC Evo 4G, and I use my smartphones very very heavily, and without external access I'm pretty much in the dark while I'm away.
Any ideas would be greatly appreciated. I am also unsure if I have port forwarding setup correctly on my D-Link DGL-4500.

Treo 750 WM6 T-Mobile and VPN

Hi all
I recently purchased an unlocked Treo 750 with use on T-Mobile. This replaced my 700w on Verizon.
I have internet working fine, MMS reprogrammed and working. However I seem to be having problems with VPN on the phone itself.
If I tether the treo to my laptop and use it as my internet connection, I can initiate the VPN client on my laptop and all is fine.
The problem is the VPN on the phone itself when using trying to use applications directly on the phone requiring VPN (ie without the laptop). I configured it, it connects fine, however when trying to use IE or remote desktop it fails to connect.
I get a 503 error in IE on each url I try through the VPN. Makes me think it's trying to hit a proxy of some kind outside of the connection manager.
I've also tried using internet2.voicestream.com as opposed to the default wap.voicestream.com... both function identical and at same speeds. I have the total internet add-on data package.
Remote desktop fails with network not found... which kind of hints at a proxy also.
Note that I do not have any proxies set in the Connections manager, makes me think there is something hard coded.
I have checked the registry for the AutoEnable thing for proxies, but in WM6 this is already set to a value of 1.
Any advice is welcomed
If it is a PPTP VPN connection you are probably screwed, it is slowly emerging that there is a problem with the implementation of MPPE used in WM for PPTP VPN connections. I.e. VPN connects but NO traffic Tx/Rx.
Best bet, try and get your IT to setup the PIX to use L2TP/IPsec I have heard numerous reports that there are no problems with the implementation standard of that VPN connection in WM5/6/6.1.

Remote Desktop Cannot Connect

Hello all:
(first of all, I apologize for the double post, I erred and replied to a thread in the diamond forum)
I'm having problems getting my remote desktop to work. Been trying to connect since I picked up my Fuze on the 11th.
I have three different computers that I can successfully administer via my desktop. I've tried using 3G to connect, no success. I've tried using Wi-fi to connect, no success. I've used local computer names, IP addresses, properly forwarded ports --
It has to be a setting I'm missing on the phone. Any ideas? TIA
What version of Windows are you trying to connect to? Do you have a Firewall? And have you done the port forwarding on the router?
But the only options you need is Computer: IP Address and the user name and password. Use a Domain if you are connecting to PCs on a domain. Also when I logged in not using 16bit color under options the PC was almost unusable.
My attempts
The things I have tried since my post:
1) attempting to connect to Windows Server 2003 machine, non-local. Used IP address with port, same IPort that works from my desktop. Left username/password blank -- filled them both in -- left the domain name blank -- filled it in. All failed. Get the error message with three possible causes listed. Connected to my home network via wifi, data connection disabled (sometimes causes problems with my internet browsing if they're both enabled)
2) attempted to connect to a local machine, running XP Pro. Again, tried all possible combinations of username/password completeness, no success. Using Wifi
My local router does have a firewall, and the remote router does as well. I can successfully navigate those using my desktop (or laptop, for that matter)
GTO: I appreciate the quick reply...thank you.

Okay its been awhile since I used 2k3 sever. Using 2k8 lately but are you trying to use Terminal Server? and if your using 2k3 and you have ISA enabled I know it can be a pain to do port forwarding with it. But let me get this stright. You have no issues using XPs Remote Desktop to log into the server machines Terminal Server/Remote Desktop? Here is an idea. Whatever port your running Terminal Server/Remote Desktop type the IP Address with a : and port. IE 192.168.0.1:3000
Also if you would like you can PM the IP address of one of the Machines and I will try from my phone that I know is working with my machine. I am pretty sure you don't need to end a user name or password and it will bring me up to the login screen or you can make a temp account. On also on the Win2k3 machine I am pretty sure you have to add the option to login with Terminal Server even if its the Administrator account.
I am able to connect to my local XP machine over wifi using the ip addy/no port. Hostname (DNS) connection attempt failed, though. My 2k3 server's power supply died or I would test that for you.
No special router config (port fwd) for my device had been done.
The fact that you can't get to your local box on your local network is where I'd start.
Local Network Issues
Thanks again to you both...
I think that might be the problem -- the local network setup. I can connect via wifi, and browse the web. However, I can't install a network printer using the WinMo app that's included, and I can't seem get to the local PC even when I use the local IP instead of the DNS name. I did check, I'm being issued an IP address by the router (obviously), but still no dice on anything relating to network based traffic.
Is there a way to ping using WinMo? I'd like to be able to use that start.
Cont..
Also, I've noticed that I don't get the same error each time. Depending on which machine I'm trying to connect to, it'll give me an error with either two or three options as to why it's not working. Trying to figure out what that's telling me.
As far as Terminal Services are concerned, when I connect from the desktop, I believe I'm using Remote Desktop there (honestly, I haven't been paying attention -- I just use whatever pops up when I type 'mstsc' from the Run dialog, lol), and I can connect to the 2003 server. However, I can't play with this anymore today, because apparently the server is down, and I won't be able to get to it till Monday.
I think I'm going to go play with the ATT proxy and see if that changes anything. I think mine is still enabled because I read that it might help with the GPS problems...
I have found some freeware app... pocketping 1.6 and microsoft has a network tool offering which I am not sure will work on WM6. I have no exp. with either tool on WM.
Can you get to your http/https router mgmt interface from the device? Check your router's client table? Does your router have any logging capabilities?
Sorry, more questions than answers.
Router
I am able to "dial" into the router from my phone -- it shows the HTCP4600 in the clients table with an IP of 192.168.2.108 ... all good.
My logging on the router was disabled, but now it is enabled. What should I be looking for?
I think i'll try the pocketping...
Now make sure inside of the router then you have all the correct ports forwarded.
It should be port 3999 to 3999 On UDP and TCP and then your PC ip behind the firewall.
Pocketping, JETCET Print 5, and success
Here's the update:
Discovered that by disabling the AT&T proxy on the Fuze, I was finally able to connect to my network printer -- the Fuze doesn't have the drivers for my printer, but that's another thread.
So I was able to make my first IN-Network contact. Installed pocketping 1.6, and it's a very useful tool. I'm able to successfully ping the computers on my network now that the proxy is disabled -- an voila...I can also connect to my laptop on my own network! The main trick was to use the network IP address and not the DNS name.
Thanks to both of you who helped out.

[Q] Wi-Fi phone configuration & my network

I have a 16-node network (used mostly as a cluster computer for meteorological work), Ethernet, 3 switches, all through an ActionTec DSL gateway/router. There is an edge machine with dnsmasq for dns cache'ing and firewall. My ISP assigns three IP addresses, one of which is my network's gateway address. The ActionTec has DHCP turned "on" although I use SNAT, DNAT, and masquerading on my side. I use my internal network to serve an Apache Web site as well.
The Wi-Fi (and other reception, for that matter) is not very good here, so I bought a TrendNet TEW-636APB Wireless Access Point. It's plugged into one of the switches. The Linux hosts and hosts_files are correctly configured and dnsmasq is configured to assign an IP Address to the TEW-636APB based on its MAC.
Everything works just fine, but most importantly, the HTC One (T-mobile) has no Internet connectivity, even though I can read the IP Address assigned to the phone. Everything is on the same subnet, by the way.
Any suggestions to get Internet up and running? I regularly use bash and c-shell as well as other languages but this one has me stumped. Any suggestions?

Minneapolis, Minnesota
Additional Info for Wi-Fi Issue
I ruled out some issues in the meantime. The TEW-636APB seems to work fine. I changed each of the config options: same problem. BUT, a laptop connected using Wi-Fi for data works just fine!
On the smartphone (that HTC One), the only URL that connects is on my own network, that is, the Web site served on my subnet and inside my network works just fine. Anything outside of my network fails.
When I turn off Wi-Fi on the cell phone (and use T-Mobile), the Web works just fine.
Very confusing. Any suggestions?

Hi Michael,
It seems to me like this a DNS problem, you should try opening google using it's ip address ( try using http ://173.194.35.132/ ) to check connectivity. Also if your phone is rooted you should be able to use some terminal like tool and try to ping some hosts to rule out the dns problem.
Cheers,
Stefan.
P.S.: please use thanks if information was helpful

Turning an android into an FTP?

Hi All,
I am currently working on something, which sounds simple in some respects.
I need my spare android phone to act as an FTP Server - Easy enough done on a LAN, but I need to make it accessible across the internet, as I need to get a service I use to send files to my phone via FTP (its a long story, but the service can only email large files automatically, and they exceed the average 25mb size limit - or they can FTP - no other transfer method is available). I also need to use my mobile, as all the internet access I have whilst on the move is via my mobile, and I cannot setup the network at home to do port redirect, so its basically the phone has to be the ftp server (and seemingly the router)
Rather than buying an FTP and webspace, I have read up on a few things that can be done. I have downloaded "My FTP Server" and set that up on my device, which is accessible over the LAN. I then downloaded Port Forwarder, and configured the incoming port, redirect outgoing port and the loopback IP of my phone to direct traffic.
I then signed up to http://freedns.afraid.org/ and created a subdomain, which when I input the current IP Address of my device on the Internet, resolves correctly, so it can see the IP correctly.
Theoretically, I can see no reason why this is failing. I appreciate the limitations are the network will by default disable ICMP Ping requests, and the IP address is Dynamic (though I can change it on demand as and when I need the files!) but beyond that, I cannot see what to do here.
Anyone got any suggestions?
The device is as follows:
Landvo L900
Dual Sim, 3G and 2G
Android 4.2.2
Device is rooted
I appreciate any advice you can offer!

Cannot access local lan web site (sometimes)

I have various machines on my lan in 192.168.1.*, I have a local DNS server to give those machines names. This normally works great, but my new Samsung Galaxy S21 sometimes says "cannot access" when I point it at a web address of a server running on my lan. I'll use a network utility app to do a DNS lookup of the other system, and it will tell me the correct address, then I'll use the same network utility to do a traceroute, and it will try to talk to a local IP I do not have in my network, in my DNS database, or anywhere in the set of addresses my router knows about. Where does this ghost address come from? Does the phone imagine that is the gateway it ought to be using for some reason? (The router's DHCP server certainly doesn't claim an unknown address is the gateway).
Every time I start trying to investigate the problem in more detail, everything suddenly starts working perfectly.
Does this ring a bell for anyone? Any clue what is going on? Maybe I should assign my phone's network statically and see if it works better.
