Up until recently we had 1 public IP address. Port forwarding was configured for about 10 different ports to be forwarded to
10 different servers/computers. We now have 5 public IP addresses and I am trying to use one of those public IPs for the RDP service on
My problem is that I cannot figure out how to forward 5 different ports coming in on 1 public IP to the 5 different computers
on the LAN based on the port number being used. Each computer is configured with a different port for RDP (3400, 3401, etc.).
I have setup our web server to use one of the public IPs and all traffic that comes in on that public IP is forwarded to the
web server. I do not want to use just one public IP for each computer nor should I have to since I was able to forwarded all
of these different ports when we had only one public IP before.
How can this device be set to allow a range of ports to be forwarded to different computers based on the incoming port number using just one of the public IP addresses?
