Did anybody make work an RMI application through a Linux firewall?
I can't find the right rules to let the TCP packets sent from a
generic client over internet to go through the linux firewall built with
IPCHAINS to reach the server that is behind it.

If somebody did this task I would really appreciate an help on how
to configure the rules on the firewall.

P.S. I'm sure is a firewall rule issue, because everything was working
before I installed the firewall and now, with the firewall installed,
only clients inside the LAN can access. Client over internet are refused.
