Hi Bjoern
Thanks for the info so far. Does this mean that eth0 on the outside need to
have the mailserver real IP address, what about the clients on the inside
that use the web, will they be able to use this real ip address to connect
to the internet as well. Currently I use a different real IP for internet
access.
Thanks

Well, LVS might work for this but is clearly bloat for your means. What you
need is port-forwarding with iptables.
On the firewall do:
iptables -t nat -A PREROUTING -j DNAT -i <external_internet_interface> -p
TCP --dport 25 --to-destination <my_internal_exchange_server>:25

Bjoern
