[SLUG] Setting up fire wall for filemaker pro server

[Mehmet Yousouf <mehmety@xxxxxxxxxxxxx>]

Hi,
 I want to allow connections to an internal (192.168.0.x) filemaker server
(on a G4 running mac 0s 9.1) through a linux based firewall (iptables) I
have tried forwarding ports 591, 5003, 2399, 660 (UDP and TCP) Using
tcpdump I can see that the remote computer reaches the filemaker server (uses port
5003) and the server response reaches the remote computer twice (using
port 5003) then the remote computer sends the request to the filemaker's
internal ip (192.168.0.x) Does anyone know why this would occur? Could it
be a firewall problem?

Regards, Mehmet
