[plug] PPP oddity

[Kai]

Hi Jeremy,
OK, it's only a basic suggestion but one that's so basic a lot of people
forget it.
I assume your using Linux.
Have you tried at root:
route add defaul ppp0
to tell Linux what your new (default) gateway is?
Also if you want IP Masquerdaing:
ipfwadm -F -a m S 192.168.0.0/24 -D 0.0.0.0/0
for 5.2
or
ipchains -A forward -j MASQ -S 192.168.0.0/24 -D 0.0.0.0/0
for 6.0 or above.

Hope this helps !

Kai
