Have you loaded the ipt_conntrack kernel module on the iptables host ?
If not, compile that as a module and give it a shot..

I have a linux IPtables firewall (latest version) that is in bridging mode.


There is another firewalling device behind it that is performing NAT.  When
a host behind that firewall connects to a PPTP server on a routable IP
address,
it appears that the IPTables linux box is breaking the connection.  When we
remove that device, the connection works fine.

Does anyone have any thoughts on what might cause this behavior?

Thanks!!
