[vpn-help] Huawei E160 using VPN - after connection loss - Traffic stops completely - related to DNS proxy daemon (still exists with v2.1.6)

[Andreas Allacher]

First I want to add that I am using Windows XP SP3 (forgot to mention 
that before).
Also: Once the problem occurs and you STOP the ShrewSoft DNS Proxy 
Service I get internet connection again. However, once I start that 
service again it stops working (again).

Regarding route (I currently only have the one from after the issue 
starts, however, I have one with DNS proxy stopped and one with it 
running - at first glance they seem identical) -> attached as text files.

Something different: I am not able to get the normal internet working 
after I connect through VPN. Isn't it possible to set the client up to 
use the normal internet connection for everything - except a certain IP 
range?
Furthermore, even if I provide a correct DNS server (in the VPN network) 
it isn't working.
What am I doing wrong?
Furthermore, I noticed that the VPN client sets the default gateway for 
the virtual interface to the same IP as the interface's IP. Can I change 
the gateway somewhere because I think it might be related to this.

Regarding logs: Do they contain any sensitive information like used PSK 
or something like this? If so I don't want to post them to the public - 
of course. Do you need a whole packet dump or are the normal enough..?

Regards,
     Andreas Allacher

Hi Andreas,

It would be helpful to see log output from when this problem occurs ...

http://www.shrew.net/support/wiki/BugReportVpnWindows

It would also be helpful to see your route table before and after this 
problem occurs. You can obtain this using the 'route print' command. It 
is possible that something isn't being cleaned up properly.

Thanks,

-Matthew
