I am using mdk9 for port forwarding and it has been completely flawless..

but i used gShield as the firewall and just tell it what ports to forward to
where..

its very easy...

Subject: Re: [expert] packet forwarding unstable


Hi,
   I've had similar problems, and running sdhorewall, so I don't think it's
the firewall software. Only some packets seemed to be dropped, some sites
just would not load. This was a temporary setup before I installed MNF on a
separate box, so I didn't pursue a solution.
