We have just installed a new Cisco 2811 on a different private IP from our primary gateway and configured it with another public IP so that we now have two gateways to the internet. This works well.
The problem is VPN connections. At first when I setup the VPN on the Cisco Router and established a connection, I could not see the servers. I could see other workstations with shares.
After some trial and error I found out that the reason that I was not seeing the other computers was that their Default Gateway was automatically removing the new static gateway assignment. An IPCONFIG /RENEW fixed this but as soon as a computer connected from the other gate way it would cause the new gateway assignment to disappear.
So now I am trying to use two NICs with different IPs and Gateways and now the second NIC is losing the Cisco routers gateway. It just goes blank in the IPCONFIG…

I checked my routing tables and both gateways are in there for both NICs…

The routing table seems to have a default gateway which is off on its own but I do not see a way of adding to this or changing it.
I suck at this networking stuff so if any one can help me out it would be appreciated.
