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.
