6112 Problem

[DeathToYou]

I have a serious problem with port 6112. I've read the post about port forwarding, I went to the specified site and I've done what it was saying there (my router is the intracom jetspeed 520i model).When I run nettest every port seems to work properly except for 6112 where it says "nat detected" (really, what NAT means????). I don't know what else I can do. I have configured the windows' firewall, and even turned it off to run the test, but nothing works. I don't have another firewall and there is no spyware or virus in my computer since I've ran some anti-anything tests a few hours ago. Any help would be appreciated, because since I bought this router I can't join most games in the internet.

look through your router's documentation for "DMZ" - put your computer in the router's DMZ and try again.

If every port except for 6112 is incorrect, you may have put the wrong IP address in there. You may want to make sure you're putting the correct IP number for your computer in the port forwarding- if you're in doubt, go to a MS-DOS window (Start->Run->"cmd"->Enter) and type "ipconfig" and hit enter. That will tell you the IP address your router gave to your computer.

What's DMZ? I have searched through my documentation and my router's online help and I have found nothing. The help does not have a search tool, but I think I should have seen it somewhere, if not in the help, in my router's settings. I looked ipconfig and it says that my IP adress is 192.168.1.2, my mask 255.255.255.0 and the last thing it says (well, it's in greek and I don't know the proper translation, maybe it is something like pre-set port) is 192.169.1.1. In every port I configured I used the port 192.168.1.2 and it worked except for 6112. And one more thing, what's that NAT?

DMZ stands for "Demilitarized Zone" (as in a place where the armed forces are kept out) - in this context it means that the router stops using any of its security features on traffic to and from your computer, meaning that you lose the protection granted by a router but also dont have to worry about blocked ports and so on.

There are instructions on setting one up for your router here (http://firewalling.com/intracom/jetspeed520i-DMZ.htm).

To answer your quesiton about NAT, it stands for Network Access Table (Or something to that effect). Basically, if you have more than one computer plugged into a router, it has to know where to send everything that comes in... for connections that a computer plugged into it starts, it knows enough to forward everything to that computer for that connection. But if a connection that none of your computers started comes in, it has no idea which computer (if any) should get it, so you have to tell it to forward certain ports to certain computers.

The NAT takes care of both of the instances above, keeping tabs on what should go where.
