i think you need to configure /etc/ipnat.conf ( read 'man ipnat' ). this is
a example definition:
rdr em1 0.0.0.0/0 port 2223 -> 192.168.1.96 port 22

( this redirects incoming traffic on outside-interface em1 port 2223 to an
internal machine on port 22 )

also, include "firewall_nat_enable" in your rc.conf ( read 'man rc.conf' )

to configure the settings from ipnat.conf, run "ipnat -C -f /etc/ipnat.conf"

regards,

usleep
