how to configure the policies to do a PURE NAT for and from overnet ?

consider 2 PC behind a firewall connected to internet by a DSL modem ip=

1/ = overnet tcp/udp=4662 udp:4665
2/ = overnet tcp/udp=5662 udp:5665

how to set the policies to do a pure nat / translation ???

the ports mapping settings is a bit strange on that firewall ...........

look at the picture, its my actual policies and seems to works ... but not at 100% ............

I'm using eDonkey behind a Kerio setup, so the principle should be the same. It's working great. My rules look similar to yours, but with a few differences.

First of all I have the destination set to be the firewall host (because all traffic to listening ports coming from the Internet goes first to the NAT server of course).

Next in the translation column I haven't specified a target port. That way the port number will be left as is and only the IP address will be translated.

Finally, you need a rule allowing outgoing traffic from the hosts. I can't see if you already have that or not, but it needs to be:

Source: +
Destination: (your internet interface) or Any
Service: Any
Action: Allow (of course Razz)
- Source NAT: Translate to address of outgoing interface
- Destination NAT: No translation

Hope it helps,
