I'm on Fedora 9, with NetworkManager-vpnc-0.7.0-0.11.svn4326.fc9.i386

I used entries like this in the routes table gui thing (nm -> VPN
connections -> configure VPN, click VPN tab, click vpn connection, click
edit, click IPv4 settings, click routes):

address  netmask     gateway   metric
x.y.0.0 255.255.0.0
f.g.0.0 255.255.0.0

With nothing set for gateway or metric.

Note: I haven't been able to find the file with this data! It was easy to
find with earlier versions, it's a real pain to add a lot of routes, plus
you can't cut and paste via the gui form.

AFAIR, I could not get a netmask of 255.255.255.0 to work, I didn't try
anything other than that and 255.255.0.0. All public addresses can
be reached via the VPN I'm using, so it does not hurt me to route more
addresses through it than required.

I do NOT have "ignore automatically obtained routes" checked (I thought I
had it checked but don't).

But ... nm vpn is broken for me (as posted here recently), so I've been
using the cisco VPN (the non-NM vpnc works fine).
