I would like to route all requests to 123.123.* normally through eth0 and everything else through VPN (tap0).
This should probably be done with iptables. Any ideas how?
Thanks
You can do this with route.
route add -net 123.123.0.0 netmask 255.255.0.0 dev eth0
route add default gw 10.8.0.1
Assuming the gateway on your VPN network is 10.8.0.1
