You should know that others have mailers that are thread enabled. This
means that when you compose a new mail, but you that the reply sort cut
others may not read this, because it end up in the list.
I redirected the mail to questions@ becuase this is not related to the
stable development brance.

You proberbly can not have two lines.

Yes, but you made some mistakes:
1. You have two lines, where only one is allowed.
2. The file format is wrong: should be tcp forward_ip:port port
3. You made a typo
4. Did you setup ipfw?
I've done this with a seperate config file.
firewall_enable="YES"
firewall_type="/etc/firewall.conf"
natd_enable="YES"
natd_flags="-f /etc/natd.conf"
natd_interface="fxp0"
/etc/firewall.conf contains:
add divert 8668 ip from any to any (note: src_ip and dst_ip changes
here, so keep this in mind if you
add rules)
add allow ip from any to any
/etc/natd.conf contains:
redirect_port tcp ip_to_goto:port local_port
Did you setup ipfw and directed packes to natd?
You also need to setup i
