Hi,
  Just create a file for the natd configuration (i.e. /etc/rc.natd):
-------------------------------------
/etc/rc.natd:
#!/bin/sh

# Natd Configuration File
# Global Configuration Directives
dynamic	yes
use_sockets	yes
same_ports	yes
unregistered_only	yes

# Port Redirection Rules
redirect_port tcp <internal>:9999 <external>:9999
redirect_port udp <internal>:9999 <external>:9999

# Address Redirection Rules
redirect_address <internal> <external>
-----------------------------------

  Then in your rc.conf file, just add (or change) the following line in
rc.conf:

/etc/rc.conf:
natd_flags="-f /etc/rc.natd"

  This will redirect a single port, or an entire address to the internal
machine.  Just make sure that if you redirect the port _and_ you are not
running an open firewall, then you will need to add lines to your firewall
configuration to allow traffic to the internal machine on the port that you
assign.  Let me know if you have any questions.
