[afnog] Natting

[Hyeroba Peter]

Hi all,

I am having some trouble configuring NAT. 

Here is my situation. I have a CISCO router providing broadband internet, it
has one public IP. I have two servers on my internal network, a mail server
and an asterisk box, I have created two domain names to identify these boxes
e.g mailserver.domain.com and asterisk.domain.com. Is there a way I could
configure NAT on the router such that if someone sent me say a mail message,
it would go to my mailserver? 
I have added both domains to my DNS records and the mailserver.domain.com is
an mx record. Also how can I be able to access both those machines from the
external world using SSH being that they have no public IP's? Can NATing
solve these issues?

Kind Regards.
