--snipped-- use ipchains or iptables and use "portfw" i do the very same thing on my redhat NAT server, below is my=3D ruleset as an example /usr/sbin/ipmasqadm portfw -a -P tcp -L $IPADDR 21 \ -R any_ip_here 21 /usr/sbin/ipmasqadm portfw -a -P tcp -L $IPADDR 20 \ -R any_ip_here 20 $IPADDR is the IP that the request is going to the second line is sending that request off to whatever up you=3D want, with port i believe you enable portfw'ing with: /usr/sbin/ipmasqadm portfw -f but it has been awhile since i set this all up ~Red Knight
