redirect 2 websites to use VPN Device

[jmandallas]

Hello everyone,
I am having a hard time figuring out the corret routes to use here.
Here is my topology Network > 3600 router > PIX firewall > router to internet.
All of our web traffic goes out the defaut gatewat(3600 router). I have a VPN device on the local network, I need a router on the 3600 router that redirects traffic going to 2 IP addresses to use the VPN device as the gateway.
I added the following routes to the 3600 router
ip route 170.x.x.3 255.255.255.255 192.168.20.250
ip route 170.x.x.2 255.255.255.255 192.168.20.250
192.168.20.250 is the internal VPN device.
when i ping either one of the addresses 170.x.x.2 or 170.x.x.3 I get the following responce from the VPN device: Reply from 192.168.20.250 Destination net unreachable
So it is going to the VPN device but seems to be looking for a net instead of a host.
I'm trying to get to a host not a network.
Sorry to ramble just wanted to give as much info as possibe.

thanks for any help you can offer,
