I have the following problem.
We are using Dynamic DNS to access our site and the modem/router differentiates via port forwarding what server the query goes to based on the port number ie all request go to abc.dyndns.org:port number.
Based on the port eg. port 3389 goes to server1 (192.168.0.1), port 8080 goes to server 2(192.168.0.2), port 80 goes to server 3 (192.168.0.3). This all works well if you are entering from OUTSIDE the local network.
INSIDE the local network, I have setup a Forward Lookup Zone on a Domain server using DNS where the Host A resolves abc.dyndns.org to the local IP address of server 1 (192.168.0.1). This works fine.
How do I get the abc.dyndns.org:other ports to go to the other servers IP addresses as you can only setup one Host A record of abc.dyndns.org to one address 192.168.0.1, if someone queries from INSIDE the local network as the modem/router does not come into play?
