In my home, I have a single Comcast modem connected to a D-Link router. The domain name myDomain.com points to my Comcast IP (yes, I know this is probably not okay, but I am only using it for personal testing with very little bandwidth, and have another server for production). The router is connected to several PC clients and two Linux servers. The Linux server static IPs are 192.168.0.200 and 192.168.0.201.
I've set up virtual server (i.e. port forwarding) to pass ports 21, 22, 80, 443, and 10000 to 192.168.0.200.
192.168.0.201 is just a PHP based fax server, and I wish to access it also using HTTP (i.e. Port 80). But I can't use Port 80 since I am already using this port for 192.168.0.200.
So, would I just access the fax server using
http://myDomain.com:123/sendAFax.php and create another virtual server to forward port 123 to 192.168.0.201? Which port number should I use? Or is there a better way to do this?
