Hi,

I have two network interfaces on my laptop (eth1 wired + eth2 wireless) and both
are connected to the network. On eth2, to get things working, I need to run VPN
(using vpnc) which adds another tunneling interface tun0.

I'm looking for a clean way to mandate in my configuration:
a) All traffic for 10.x.x.x should go through eth1
b) As for the rest, use eth2 i.e. tun0.

Are there any utilities which can help ?

Here's my routing table when only eth1 (the wired ethernet device) is activated.

geeKISSexy:~# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.73.16.0      0.0.0.0         255.255.252.0   U     0      0        0 eth1
172.16.0.0      0.0.0.0         255.255.0.0     U     0      0        0 tap0
0.0.0.0         10.73.16.1      0.0.0.0         UG    0      0        0 eth1


And this is when eth2 (the wireless device) gets activated. After eth2 is up, it
executed vpnc from post-up.

geeKISSexy:~# ifup eth2=eth2foo

10.73.16.0      0.0.0.0         255.255.252.0   U     0      0        0 eth1
10.73.36.0      0.0.0.0         255.255.252.0   U     0      0        0 eth2

0.0.0.0         10.73.16.1      0.0.0.0         UG    0      0        0 eth1


So currently, still everything is being routed through eth1. Surprisingly (or
maybe not) all is being routed through VPN which was fired in the post-up of
eth2

What I'm looking for is to know, what changes do I need to make into this
routing table so that:
a) All 10.x.x.x related traffic passes through eth1
b) As for the rest (and default route) passes through eth2

Thanks,
Ritesh
