Sziasztok!

Adott egy FreeBSD 5.2.1-RELEASE, rajta egy MPD szerver figyel a 1723-
as
porton és müxik szépen. Igy néz ki a cucc:



 *******************
**************
*  router publikus ip-vel*  192.168.1.254
*VPN szerver       *        192.168.1.8
*
************************************************
*******************

A router NAT-ol  es atiranyitja a 1723-at az 1.8 1723-ra. Ez megy is 
gond
nelkul. A problema ott kezdodik, h ra kellene venni a routerra bejovo
6667-et hogy
az 1.8-ra erve o 1723-legyen. Tehat a tavoli VPN kliensem a 6667-en 
probal
kommunikalni es ezt at kellene forditani az 1.8 1723-ra.
A kovetkezo lepeseket tettem ennek erdekeben:

1. /etc/natd.conf

unregistered_only
same_ports yes
interface dc0
use_sockets
dynamic
log
redirect_port tcp 192.168.1.8:1723 192.168.1.8:6667
redirect_port tcp 192.168.1.8:47 192.168.1.8:47
redirect_proto gre 192.168.1.8

2. /etc/rc.firewall

ipfw -q flush
ipfw add 01000 divert natd ip from any to me in via dc0
ipfw add 01002 divert natd ip from 192.168.1.0/24 to any out via dc0
ipfw add 01004 allow gre from any to any

Jönnek is a csomagok szépen csak úgy néz ki h a GRE csomagok nem 
mennek
kifele és nem jön össze a kapcsolat végül.
