Have you tried to set a default route to the IP address of the tunnel 
interface at the main network:
ip route add default via a.b.c.d
where a.b.c.d is the IP address you gave to the tunnel interface at the 
main network end.

this is also called RPF or reverse path filtering, and is sometimes used
as a partial countermeasure against spoofed ddos attacks
