How do I forward ports to multiple IP's on Apple Airport Router to host Farcry?

Simple Explanation:

Look at the screen shots below, how do I forward those ports to more then just the one network IP of 10.0.1.3? I want to forward those same ports for 2 other computers in the same house which are 10.0.1.7 and 10.0.1.12.




Long Detailed Explanation:


Check out the screen shots below, friends and I are trying to play the old school Farcry game online. In order to host a server and have people be able to connect to you, you have to forward TCP (49001-49002) and UDP (49001-49002, 49124).

My friend would create a Farcry game server and when it showed up in my Farcry server list it would be grayed out and I couldn't connect. After searching online I found out he had to forward ports in his Apple router for me to be able to join his server. So I logged into his computer and forwarded the ports for his network IP which you can see in the screen shot is 10.0.1.3. After I forwarded the ports he could create a server and people were then able to join.

But there are other people in his house that want to play Farcry and be able to create and host a Farcry server. So I figured I could just repeat what you see in the 1st screen shot below and just replace the network IP address with the other people in his house that want to host which are 10.0.1.7 and 10.0.1.12.

But as you can see in the 2nd screen shot, it gives me an error if I do that saying those ports are already forwarded...but they are forwarded for a different IP. I want to forward those ports for multiple network IP's that way more then one computer in his house can host a Farcry server and have people join. How do I do this?

Simple answer - you can't forward the same ports to two different internal IP addresses. It's not how NAT was designed. Try enabling uPNP and see if that works or port triggering.

I don't think there is any port triggering options in the Apple Router setup. I will have to look for uPNP, I don't know what that is but I will try it.

So there is no simple way to do this?

uPNP (Universal plug and play). When enabled, this permits the router to automatically detect port forwarding requirements, and to automatically forward ports as needed by applications running on computers on its network.
