Hi Hyeroba,

The ip nat inside source static tcp 192.168.0.98 25 41.x.x.2 25 extendable
statement
Creates a static nat for the private ip of your mail server in this case
assuming it to be 192.168.0.98 to your public IP also assuming it to be
41.x.x.25. You can only test this outside of your network

HTH

Cheers,
Peter

Thanx Peter,

Have added to the router the changes you suggested and did the same for one
of the boxes. When I try to telnet to the mail server e.g. telnet
mailserver.domain.com 25, I get connection refused, unable to connect to
remote host. 

Just for clarity, this is an extract from my configuration,

ip nat inside source list list1 interface Serial0.1 overload

and the access list I created based on your advise,

access-list 1 permit 192.168.0.0 0.0.0.255

might there be a miss match since my access list is called "1" and my ip nat
declaration is called "list1"?
