We have noticed a problem with PPTP forwarding not working as it should.
We have a system on kernel 2.4.24 with latest pom and iptables 1.2.9. There is a port forwarding PPTP to a windows 2000 server behind the firewall.
We noticed that when someone connects with PPTP the connection is closed after 3 to 4 minutes. This problem only occurs if there is a router in nat mode between the firewall and the internet. If the public ip is on the firewall then this problem does not occur.
Can this be solved in the firewall or will we have to install another router (in bridged mode)?
