Hi all

Kinda stumped - what I want to do is setup a route to a website using a
router that is on the end of a (firewall-firewall) VPN.

The problem is a website, due either to their networking errors or possibly
restrictions is not visible to PC's on our network from one office but is
available from our other offices (been through contacting ISPs and website
admin - either no response or nothing they could do).

What I thought of as a workaround is to setup a static route over the VPN so
that PC's from the affected office use the router (firewall) from one of the
other offices.

My problem is that I cannot setup a ROUTE ADD as it will not accept the
other subnet's firewall as a valid router.

Example:-
Internal network 192.168.1.0, default gateway 192.168.1.254
VPN to other office network 192.168.3.0, default gateway 192.168.3.254

ROUTE ADD {website address} 192.168.3.254 fails with error - The route
addition failed: Either the interface index is wrong or the gateway does not
lie on the same network as the interface. Check the IP Address Table for the
machine.

Any suggestions?

thanks

Derek
 
You can't add a route directly to a node on another network. You route to
the next hop, which should be aware of the other network.
