I have 2 servers at home. My domain is at changeip because I do not have static IP. I want to expose one of my systems to the internet.
currently my DDNS entries look like
mydomain.org x.x.x.x
smtp.mydomain.org x.x.x.x
www.mydomain.org x.x.x.x

All of these x.x.x.x refer to the same IP address (whatever my current IP is)

I have a network at home that has several workstations that get their IPs from smtp.mydomain.org (locally known as 192.168.2.1) through DHCP (they are on 192.168.2.y). There is also another server at 192.168.2.50 (fixed locally). I cannot see this from the outside. I want to see that server from the outside. How can I put some of my work on 192.168.2.1 and some on 192.168.2.50. I would like the outside to know of the first system as smtp.mydomain.org and the second system (currently invisible) as fserver.mydomain.org. These systems are both Linux systems. The one that I can see has a program named DNSMASQ running and also DHCP running. DNSMASQ is described as a DHCP server and a NAT server in its documentation. Thanks in advance

Since you're doing PAT, you can only do port forwarding in your router to specific hosts.

Assuming smtp.mydomain.org is using SMTP and fserver.mydomain.org is using HTTP, you would map

25 -> smtp.mydomain.org:25
80 -> fserver.mydomain.org:80

You could even map multiple servers like this:
8008 -> webserver1.mydomain.org:80
8080 -> webserver2.mydomain.org:80

It depends on your router how you do port forwarding. For DDNS, just set both host names in the same update set and have one of your servers update the records (one can be a CNAME of the other).
