GameRanger Behind Symmetric NAT - 18.Mar.2012 8:00:02 PM

I have been having a weird issue with GameRanger. I can log in and see various servers of different games but when I try to connect to any server or host my own server, it says that I'm behind a symmetric NAT router (Which I think is my ISA server), due to which when I get into the game I cannot see the 'game server' which my friends have hosted (The server list in the game remain empty). They can see each others server but I can't find their server because of this problem. When I looked at GameRanger own support it said that I need to port forward 16000 (UDP).

Now, I want to tell you that I don't have any port restrictions in place. All ports are opened. I have even placed a separate firewall policy for allowing port 16000 UDP to be forwarded but it was to no use. I still cannot view my friends server and they cannot join mine even when I host it.

When I disconnect my ISP LAN cable from the ISA server and connect it directly to my PC the problem no longer persist. I can join them and they can join my server. But as soon as I plug it back to the Server machine I start getting this problem again.


Any step by step guide will be HIGHLY appreciated.

P.S: I'm running ISA Server 2004 on Windows Server 2003.

I forgot to mention one thing. I don't have any ISP router which is providing internet access to my ISA server. I have a CIR based connection and my ISP provided me a Fiber to LAN media converter only. Which is connected to one LAN interface in the server. The other LAN interface is connected to a switch, which is providing internet facility to the users.

The hustle and bustle and neat cries accompanied by trumpet far away, which lasted several minutes and then suddenly quiet.
