Over the last few hours, my phone tethered has allowed me to ping external clients via their IP, but not their domain name. I can even use nslookup to change the name server to 8.8.8.8 (google NS), which pings successfully, but fails to act as a DNS server.
Data on the phone is fine, but tethering is very sporadic. A few times was able to get some web pages via IE and Firefox, but now things seemed closed.
This is via both USB and Wireless, ICSControl and built-in ICS for WM.
Right now I'm only able to tether by using a http proxy server.
But, without the proxy server, I'm able to browse websites via IP address. Very strange. It's almost as though port 53 is blocked, or maybe just UDP all together is blocked?
Anybody else having DATA problems tethering?

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.
Hi there!
Maybe I'm just too stupid, but I've benn trying for weeks now to setup the network parameters for my University's Campus network and failed miserably, so could someone please explain to me how this darn "Internet Connection Manager" works?
What I need in brief:
How can I setup a proxy to use with and only with
- HTTP(S) and FTP(S)
for a WiFi-Network that
- is NOT encrypted
- does NOT require dialing a number / accessing a modem
- does NOT use a VPN
??
Whenever I try this it always results in the connection dying completely.
In other words: When I select my standard UMTS-uplink as "default connection for programs connecting automatically" and then manually establish a WiFi-connection I can reach all computers available on the campus network get ping responses and everything, but I cannot use a proxy, hence not load off-campus pages.
When I define a new connection and enter my settings (just WiFi-name and the proxy details) I can still establish a WiFi-connection, but get a ping timeout even on the access point and the intranet servers usually available through the WiFi. No SSH login, no intranet, nothing (but I do get an IP assigned & stuff)
Here's what I would like to do in theory:
=> Manually connect to a WiFi-Network called "tuwlan".
. -open network
. -no encryption
. -IP, netmask, gateway, nameserver etc provided automatically by DHCP
=> Establish a SSH2 (SecureShell) connection to our on-campus proxy server and tunnel some ports to get through the Subnets (extremely restrictive) firewall.
. -SSH including port forwarding done with PockeTTY, works like a charm
=> Use Opera Mobile to surf web pages and FTP Sites through the proxy "localhost:40081" (which is forwarded to our campus proxy server through SSH2).
=> The Proxy only knows HTTP(S) and FTP(S), so all other programs (ICQ, Skype etc) are not to use it!
This setup used to work great with older Opera versions, but they removed the proxy setting dialog in favor of directly using the ICM settings.
So now I'm stuck with Microsofts Internet Connection Manager
Can anyone please help me to get this working?
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.
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?

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?

Might be a DNS problem...

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
This started a couple of days ago, and I have now mitigated it with a couple of firewall rules on the VPN gateway, as well as shutting down the dhcpcd server on that server (which I don't need anyway, and which probably should have been stopped long ago).
My LAN has a raspberry pi 4 running their debian firmware that is configured as a VPN gateway. It connects my LAN via ProtonVPN to the internet. This gateway is set up with a static IP address (192.168.2.49) on the LAN, and is configured to use another RPI on my LAN to get its DNS (192.168.2.50).
My one month old running OOS 11 OnePlus8 is rooted with magisk, and I have blocked most of the google stuff from the internet using afwall, and suspended non-essential system services using greenify. When connected to my LAN, the phone has a static IP address (192.168.2.71), has its gateway set to the VPN gateway (192.168.2.49), and its DNS to my local rpi DNS (192.168.2.50).
DHCP on my LAN is provided by my router (192.168.2.1).
WIFI on my LAN is provided by an enterprise-grade tp-link hotspot.
Starting a few days ago, for reasons mysterious, when the phone connects to the LAN, the VPN gateway would promptly go offline. Because I run it headless, I would be forced to reboot it - which made diagnosis a bit of a pain. Finally, I found a log entry on the VPN gateway that informed me that my OnePlus was trying to claim the ip address of the VPN gateway as its own (192.168.2.49) in spite of being set to use 192.168.2.71. This duplicate IP was causing dhcpcd on the VPN gateway to immediately take down its eth0 interface. This would break ALL connectivity because I have wifi on that RPI disabled.
Prior to this problem involving the OnePlus, that RPI had been up continuously for over 400 days, so it should certainly be considered to be reliable at the job it does and almost certainly the problem is with the OnePlus.
So, for some reason the OnePlus is trying to assert its assigned gateway address as its IP rather than the 192.168.2.71 that is set, at least in some packet that it uses to announce itself; once it is connected it works properly (which means the right IP address is being used).
I have deleted, then re-created the wifi connection profile and doing that did not cause the problem to go away.
I have another RPI VPN gateway on my IOT VLAN (192.168.24.0/24). No DHCP is available on the VLAN (a security measure), and I do have a profile for the phone that allows it to connect to the VLAN. It works without issue there, but then dhcpcd has been and remains shut down on that RPI. I suppose I could start dhcpcd on that server and see if the phone then breaks it too. I won't do this unless there is some merit to doing so...if it would help find the basic problem.
As I say, shutting down dhcpcd and blocking all dhcp traffic to/from the LAN VPN gateway mitigated the problem. But that the problem could occur at all says something is wrong, and I'm pretty sure it isn't a problem on my network.
This seems most likely to be a bug in OnePlus firmware, though why it would manifest after a month is a mystery to me. Does anyone have any insight? Or does anyone have any suggestions for another place on XDA where this post might more appropriately be placed?
I was pretty sure no one would have any idea about this. I have mitigated it by turning off dhcpcd on the VPN gateway and I am not inclined to do a deeper dive; I have too much else to do.
