I have created a port forwarding rule that forwards anything with a destination port 4000 entering 172.25.1.2 to an IP of 10.134.1.197. The second lan card has an IP of 10.134.1.249. I see the trafic come in it says redirecting but the traffic does not get forwarded. When I turn the rule off and use a seperate port forwarding program with the same rules it works fine. Does anyone have any thoughts. I am using Windows XP with ICS on and net firewall 188.8.131.52
Windows XP ICS is not compatible with port forwarding. In the next few weeks a version 3.0 of NeT Firewall will be released. It includes NAT and traffic shaping services, so you can switch to NeT Firewall NAT instead Windows XP ICS.
