Hi there,
I need to forward all tcp packets with port 25 (SMTP) from Internet to
machine in my network. My settings (eth0 = internet IP, eth1 = 192.168.200.1
- dmz IP connected to another machine with Postfix, eth2 = 192.168.0.1 -
gateway - LAN). Have opened port 25 and setup rule :
iptables -t nat -A PREROUTING -p tcp -dport 25 - i eth0 -j DNAT -to
192.168.200.2:85
iptables -A FORWARD -i eth0 -p tcp -d 192:168.200.2 -dport 25 -m state
-state NEW,ESTABLISHED,RELATED -j ACCEPT
But it still doesn´t route tcp packets on port 25 to my Postfix computer :o(
If I try telnet 192.168.200.2 25 from FW it works, if I try this from
Internet, it doesn´t work :o( Any ideas ? Thanks a lot.
Stan.
