VPN connection causes problem connecting to web pages

[bekdik]

If you have encountered connectivity problems after setting up a VPN, then maybe this will be of assistance.

Using Windows XP, after you fire up a VPN connection you cannot browse the Internet.

Or if you have an Internet accessible web server, after you fire up a VPN (maybe to traverse a firewall), you access from the web is no longer possible.

The problem may be with the VPN connector which defaults a setting which changes the machine's gateway such that it is now unreachable until the VPN is disconnected.

The fix is simple, but subtly hidden:

Open Network Connectors
right click on the VPN connector and choose properties
click Networking Tab
double click TCP/IP
click advanced
Choose General Tab
Untick "Use default gateway on remote network" box
click OK each time it's displayed (3 times)

I hope that helped.

not a connection problem, it's a dns problem, the connecting host is using the RAS servers dns servers to resolve names instead of it's local dnscache or locally set dns servers when "Use default gateway on remote network" is enabled. It's going round in circles taking too long to resolve names, 4 - 8 seconds per resolution, per dns server in the list.
