How do I configure IPTables to allow a PPTP session to connect outbound

I have a private LAN sitting behind a Linux server. I want to allow a Windows PC on the LAN to open a Microsoft PPTP session to a remote client network (using port 1723, protocol 47[?]). I can't seem to configure my IPtables rules to allow this - does anybody have a potted solution?

This should work if eth1 is your internal network card. If that's not the case, replace it with the name of your internal card:

iptables -A FORWARD -p 47 -m state --state NEW -i eth1 -j ACCEPT
iptables -A FORWARD -p tcp --dport 1723 -m state --state NEW -i eth1 -j ACCEPT
