Thanks for including a screen shot....that helps us out tremendously.

I'm not sure of the exact problem as of yet, but with the game server in the DMZ, technically you wouldn't have to forward ports as the DMZ is designed to put a specific computer 'next' to the router instead of behind the router.

So with the .22 computer in the DMZ, all ports should be open to that computer.

Instead of disabling the windows firewall, you may have to make exceptions similar to what you've done in your router. If for some reason the firewall service gets restarted, the ports will be blocked.

As long as your virus scanner doesn't have a built in 'internet security' or firewall type of program, then I doubt there would be an issue with leaving the anti virus on....unless you're turning it off just for performance reasons.

I have a belkin router. Is your modem in 'bridge mode' ?

How do you mean bridge mode?

[clanmills]

The Modem can operate in two modes:

1) He's managing everything. He knows the username and password to log onto your ISP. He's providing a DHCP Server for the LAN, a firewall, DMZ and can port forward.

2) Bridge Mode
He becomes transparent and leaves your router to do almost everything listed above (logging on, DHCP, Firewall, DMZ and 'virtual hosts' ( = port forwarding in Belkin speak).

You should use Bridge Mode and set up the virtual servers in the Belkin Router.

what's the make/model of your modem?

[Rutger]

I've got a Belkin F5D5231-4

[AboveTheLogic]

That appears to be your router's make/model.

What about the modem? Do you have a modem? There should be an Internet or WAN port on the router, and a cable from that goes to the modem or something... what does it plug into?

motorola SBV5120E that should be the right number

I believe we found the issue.

So the modem is most likely getting your external IP. To verify, in your Belkin router's interface, is there a status tab that shows the current IP of the device. If so, is that IP the same IP you see at www.whatismyip.com or is it an 'internal ip' like 192.168.x.x?

If we can determine that the modem is the one grabbing your external IP, then you'll need to forward all ports to the IP that your router has so it can handle forwarding to the appropriate computer on your network.

Putting the modem in bridge mode in this case my not be the right answer because it might mess up your VoIP.

To access the modems interface, go to http://192.168.100.1 login/pass should be admin/motorola Within the interface, you should be able to see the status of the modem, if it has the external IP that you see on www.whatismyip.com , etc. Similar to the interface of your Belkin.

You may have to connect your computer directly to the modem before you're able to connect to that device via the http interface.

Brian-- after briefly scrolling through that manual, I don't think that modem is doing NAT... so I think its passing the internet IP to the router.

I agree the status tab on the router will tell you for sure.

Page 33 talks about sharing the connection with a hub or switch--- so at first I thought that it is doing NAT... but then it says not all providers will allow it, which makes me think that its warning you about trying to grab multiple external IPs.

I've seen this before, with Cox cable in Las Vegas--- someone connected a switch directly to the modem and got 2 external IPs. I'm not sure if the cable company charged more or how that happened, but that could be what the manual is suggesting.

Also, my old Linksys Cable modem I used to use would pass the external IP straight through---yet when I would go to http://192.168.100.1, I received the modem diagnostics page. I never quite understood how that works, maybe just a routing table.
