You've hit the nail right on the head Jim.

However, two problems.

The DHCP server is built into the ADSL router and I cannot get it to not give 
the default route.

When I try to do static routes I cannot add the route without getting the 
error.  

I can set the IP interface to eth2 no problem as 91.85.127.194
I can add the route to 212.104.130.193 on eth2, and can ping the IP address.

However, I cannot add a route to the remote site.

route add -net 77.86.27.0/26 gw 212.104.130.193

generates the error (From memory)
