I'm a scientific programmer with a loose grasp of what goes on under the hood in my small home network so bear with me whilst I try and explain using the correct words if possible.
My home network of five PCs (Windows 7, Vista, 2003, 2 x XP) uses the 192.168.0.0
range of IP addresses. My ADSL router is 192.168.0.1
and is set to do DHCP and all that good stuff. So far, so good. Most importantly I can connect to my local web server on 192.168.0.42
.
I frequently have to connect up to a client's VPN using Checkpoint SecureClient. When I do so I'm given a 10.something
IP address on the 'virtual' network card.
If I'm connected to the VPN I can no longer connect to my 192.168.0.42
web server.
How can I tell my PCs to only go via the VPN for anything beginning 10.*
and to stay 'local' for everything else?
(below added following Chris Thorpe's answer)
BTW I don't see the VPN connection under Control Panel. I just see my physical NIC. Here's what I see running ipconfig
, if that helps:

A route print gives 50+ lines of routing info. Here's some lines if that helps...
