9300em router nat troubles

[cacoulte]

Hello,
I am trying to get my router optimized for gaming and I cannot seem to figure it out.
I have the 9300em ultraline series 3 router, and I have reset it multiple times because supposedly upnp default is set to on.
everytime I check device details, it says upnp is disabled for my computer, my ps3 and my xbox.
I just DMZ the one im playing on, I dont want to DMZ my computer though.
any help is appreciated.
for example: modern warfare 2 on PC says my NAT is strict, and games mess up alot because of it.
I have tried port forwarding and I guess im not doing it right,

A few questions:

1.) Does your PC have a static IP reserved on the router?
2.) Have you mapped all of the ports found here to your PC's IP?

3.) What firewall are you running?

You shouldn't have to use uPnP for anything. uPnP is very insecure and a major hole for malicious users to access your systems. I use XBL all the time w/o uPnP forwarding enabled. When I lived with a PS3 user she also had uPnP disabled with no problems.

Have you tried running a tracert to see how high your latencies are?

1.) Its running DHCP, so that would mean its a dynamic IP? im not sure
2.) ive tried forwarding the ports if thats what you mean.
3.) windows?

I thought upnp was meant for games in particuliar to open the correct ports for those specific games.?
