NAT Problems

NAT Problems [SOLVED]

Well i got sick of not being able to join games on the 360 so i decided to look into changing the NAT type from 'Moderate' to 'Open'. I've found a few things on this, namely enabling UPnP (which was already on) and DMZ (which wasn't), so i decided this would be a good place to start. Went into the router homepage, logged in and went to the tab that said DMZ, and it refuses to load. It takes a while to get to a blank page where Firefox says 'Transferring data with 192.168.2.1' and goes nowhere.

Not just that however, it seems whenever this happens the router blocks me out, forcing a reset from the wall. This is what happens when i've tried to access the DMZ page:

Code:

ewan@ewan-desktop ~ $ sudo /etc/init.d/networking restart
 * Reconfiguring network interfaces...                                          There is already a pid file /var/run/dhclient.eth0.pid with pid 3063
killed old client process, removed PID file

and this is what should happen when i restart networking:

Code:

ewan@ewan-desktop ~ $ sudo /etc/init.d/networking restart

Which i thought was rather strange. The router is a Belkin F5D8633-4 and both me and the Xbox connect via Ethernet, although the printer and a laptop use Wireless G.

Any suggestions? I'm going out now but i'll happily answer any questions when i get back.

Nobody? I tried updating the firmware but the tool in the router's page didn't work and i can't find any new ones on the internet.

I'm thinking this might be a good time to sort out my network, spend £20 or so and tidy it up by adding a wired router (suggestions), getting some more, longer ethernet cables and getting a proper phone line cable as opposed to daisy chaining them which is what i think my dad has done to set this up.

EDIT: This might be just the ticket:

A usability problem of the DMZ has been resolved

EDIT 2: And it did, now i can get into the DMZ page

All i need to do now is figure out how to use it... i assume i need to give it a static IP? How exactly would i go about doing that?

Okay, well guess who managed to solve all their own problems? Makes you feel like a genius

Set the IP Adress of the Xbox in it's own 'Network Settings' tab to something outside of the range of my router's pool, Subnet Mask and Gateway were easy but then it couldn't find the right DNS, so i manually set both of them to the Gateway (of my router) and it worked, but left me with a Strict NAT. Go into my newly updated router's firmware and set that IP Adress (192.168.2.200) as a DMZ and voila - Open NAT!

Really need another Ethernet cable now though, i can have either the Xbox or the PC on.

That's cool mate, only other thing you could do if you wanted to free up the DMZ is port forward 3074 UDP/TCP to your 360 static IP.
