Well. this should be done automatically otherwise it would break TCP/ip. I think
you messed
up your config.
Mine setup with 2 ip''s:
rasnet:/etc/blootbot# ip rule
0:      from all lookup local
32760:  from all to 213.226.172.0/24 lookup parabole
32761:  from all to 213.252.224.0/24 lookup parabole
32763:  from all to 213.226.161.0/24 lookup parabole
32764:  from all to 213.226.147.0/24 lookup parabole
32765:  from all to 213.226.146.0/24 lookup parabole
32766:  from all lookup main
32767:  from all lookup default
rasnet:/etc/blootbot# ip route
192.168.20.0/24 dev eth1  proto kernel  scope link  src 192.168.20.59
192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.1
81.0.0.0/8 dev eth0  proto kernel  scope link  src 81.7.84.36
default via 81.7.84.1 dev eth0  src 81.7.84.36
rasnet:/etc/blootbot# ip route ls table parabole
default via 192.168.20.1 dev eth1
