Re: Dual Interface Routing Question

I have one more scenario where I think are issues without multiple routes.

When I'm at home, I connect to my office network using a VPN Connection
something like:

rrs@geeKISSexy:~ $ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
202.X.112.XXX UGH   0      0        0 eth2   U     0      0        0 eth2         U     0      0        0 tun0

Now, If my understanding is correct, the default route ends to be through tun0
and all data, except for my internal network, has to be tunneled
through tun0.

What is the path when I hit for www.debian.org in my browser ?
Does it route through my corporate VPN Network ?
