This is an old post, I posted here a couple of years ago for Arjen Halma. It was the first one I found, so i'm putting it back here for reference.

interface Tunnel0
 description tunnel to other side
 ip address <PTP-IP> <PTP-NETMASK>
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip mtu 1480
 ip tcp adjust-mss 1420
 tunnel source Dialer0
 tunnel destination <TUNNELSERVER>
 tunnel mode ipip

Add additional routes for the network on the other sides ;)
