I had a similar problem, trying to use SME V5.5 as a proxy server for three subnets on a WAN. I had to manualy add the routes using: "route add -net 192.w.x.0 netmask 255.255.255.0 gw 192.d.e.f metric 1 eth0" for each of the non-local networks. This enabled the remote networks to use the SME server as a proxy etc to the internet.
What I need to know is: How can I configure the server to automatically add these routes at boot time so that I do not need to manually enter them each time I restart the server?
Thanks,
Ian
