This is because there isn't any special configuration needed under iptables
for PPTP VPN clients.  I have several iptables based firewalls NAT'ing PPTP
traffic through them with no special configuration of any kind.  All of
these firewalls are running my firewall script
(http://www.asgardsrealm.net/linux/firewall).
