Please define, "PPP won't work".

Can you use the net from the firewall?

Does the connection drop, or do you mean that systems behind the
firewall can't connect to the net?

If what you mean is the latter, have you enabled forwarding
(echo 1 > /proc/sys/net/ipv4/ip_forward)?

Did you include the rule to enable masquerading?
$IPTABLES -t nat -A POSTROUTING -o ppp0 -s $NETWORK -j MASQUERADE

Answers to "it won't work' questions are really difficult to come up
with.
