Hi all,
I'm new with iptables, I trying to create a rule that redirect all the packets that goes to the port 25 of my firewall to the port 25 in a Internet LAN machine, then I execute the command:
/sbin/iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 25 -j DNAT --to 192.168.10.12:25
eth0 is the host exposed directly to Internet, and 192.168.2.12 is the
host in the LAN.
You should also have a FORWARD rule: /sbin/iptables -A FORWARD -p tcp -d 192.168.10.12 --dport 25 -j ACCEPT
