See man ppp under files:
/etc/ppp/ppp.linkup
Most basicly the contents of this file are executed after a connection
has been established.

I dont know what kind of firewall you're using but maybe this is
helpfull to:
Have you thought about using something like "( tun0 )". To my
understanding this means "packets that come in through a IP address
associated with the interface tun0".
