[Desire HD Q&A, Help & Troubleshooting] htc_softbank:
Hello,

I am currently running codefireX SR14. My provider is Petro-Canada Mobility. I am having issues when tethering through their "unlimited browsing service" Basically this service only allows http/SSL TCP traffic on ports 80/443.

Anyhow, I've been using autoproxy and this has allowed me greater functionality of most apps. Here lies the problem. When I attempt to tether (wifi hotspot or USB) Traffic is not being forwarded at all from the hotspot gateway. As a result, connected hosts cannot access the internet. After doing some initial troubleshooting, I have concluded the issue appears to be the OS itself.

Regardless of the situation, the hotspot gateway will not forward traffic with autoproxy connected, disconnected, or if I use my Junos VPN.

As a result I have 2 questions:

1)How does the Android tether operate?

2)Are there any "Backend" options I can access someone to force the gateway to forward traffic through autoproxy or my Junos VPN?

I have included the trouble shooting results below:

When tethered:

My PC IP = 192.168.43.83

gateway = 192.168.43.1

Ping to gateway is ok

:

>ping 192.168.43.1

Ping statistics for 192.168.43.1:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 0ms, Average = 0ms

This means my PC can reach the gateway fine (with autoproxy on and off) With that in mind, I try to ping the Petro-Canada proxy server:

Proxy server IP = 10.128.1.69

Ping to Proxy server fails

>ping 10.128.1.69

Pinging 10.128.1.69 with 32 bytes of data:

Request timed out.

Request timed out.

Ping statistics for 10.128.1.69:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

This happens regardless if autoproxy is connected or disconnected. What this means is that the gateway traffic on my phone is not being properly forwarded.

When I usb tether it's the same issue:

PC IP:192.168.42.142

Gateway:192.168.42.129

Ping to gateway is ok

:

>ping 192.168.42.129

At this point I believe the issue to be Android OS. I am running Jellybean 4.2.2, I also have Junos VPN installed, and I have full internet from my phone when connected (all ports tcp/udp) through Petro-Canada unlimited browsing. I still run into the same issue where trying to ping any outside IP results in a timeout. (i.e Google DNS 8.8.8.8)
