Hi
Newbie here so be gentle
Is it possible translate a port without specifying a fixed destination

Example
If I configure the mail server on my lan to send outgoing SMTP on say, port 2500 Can a shorewall rule forward/translate that to any host on the internet as port 25

And of course I would still require port 25 incoming to the mail server from the internet to remain as port 25

At present I have rules that only allow the mail server and no other hosts to send on 25(Dest) and thought adding port 2500 in source column would do the trick, but no

Thanks in advance
Karl
