vpn

I have an Ubuntu Virtualbox guest with two network interface, eth0 (NAT) and eth1 (bridged).

I want to connect to a PPTP VPN using eth1, but I don't know how to specify which interface to use. If i just try:

sudo pon myvpn nodetach

It fails with:

Using interface ppp0
Connect: ppp0 <--> /dev/pts/1
Modem hangup
Connection terminated.

Looking at routes with route seems to indicate that eth0 is being used:

x.x.x.x.no 10.0.2.2        255.255.255.255 UGH   0      0        0 eth0
