Hello all,

I've a range of 30 public internet addresses to manage starting, say, from 213.25.24.0 to 213.25.24.31 netmask of course 255.255.255.224.

My firewall (Red Hat 9.0, latest kernel) public IP is 213.25.24.30 the router address is 213.25.24.1 and the LAN network is 10.1.0.0/16.

I've an internal mail server, say, 10.1.1.2 which I would like to see from the outside as 213.25.24.3, one IP of my range.

Except DNS registration, what are the correct steps to make this possible?

I just set this rule on my firewall:
iptables -t nat -A PREROUTING -p tcp -i eth0 -d 213.25.24.3 --dport 25 -j DNAT --to 10.1.1.2:25

but I guess it's not enough because it's not working.

A help is really appreciated, thanks in advance.

Roberto - Italy
