Здравствуйте все.
В локалке есть фтп. На границе стоит freebsd 7.1
ipfw+natd. На фре крутиться proftpd.

В rinetd.conf:
79.175.28.46 2121 192.168.37.12 2121

При подключении из-вне виснет подключение и выдается сообщение: Enter in passive mode
А затем: 500 Invalid PORT Command

Подскажите куда рыть ?

Рыть в сторону протокола фтп, пассивного режима.

мне помогло:
в natd.conf
redirect_port tcp 192.168.37.12:2121 X.X.X.X:2121

в firewall.sh (сразу после divert)
/sbin/ipfw -q add allow tcp from any to 192.168.37.12 2121 setup
/sbin/ipfw -q add allow tcp from me 20 to any setup
