NAT and Crysys 2

[HammerON]

When I log into MP CRYSIS 2 reports (on screen) that "NAT:Strict". I have been trying to figure out how to make it "Moderate". I am not well versed in networking so I could use some help.

There is a readme file that I found:
================================================== ================
NAT/Firewall

Game Port Usage

For all traffic between server and client 'game' port is used
(default 64100 - net_lobby_gamespy_online_port).

Ports
SDK Service Hostname Type Local Remote

Available hbmaster3 crysis2.available.gamespy.com UDP Any 27900
NN natserver1 natneg1.gamespy.com UDP game 27901
NN natserver2 natneg2.gamespy.com UDP game 27901
NN nat neg Game client UDP game game*(other game)
QR2 hbmaster3 crysis2.master.gamespy.com UDP game 27900
QR2 Incoming queries Game client UDP game Any
CDKey keymaster key.gamespy.com UDP game 29910
SAKE Profile settings/stats crysis2.sake.gamespy.com TCP Any Any (def:80)
Chat Any IRC server peerchat.gamespy.com TCP Any 6667
GP gpmanager gpcm.gamespy.com TCP Any 29900
GP searchmanager gpsp.gamespy.com TCP Any 29901
SB gmaster3 crysis2.ms5.gamespy.com TCP Any 28910
SB Server queries game servers UDP Any game*(target server)
RSS RSS Feed lb.crysis2.ea.com TCP 80 80

Default value for 'game' is 64100 (can be adjusted).
For incoming UDP traffic, only port "game" ( default 64100)
is required to be opened."

But I am not sure what to do (if anything) with this info. I have a RCA modem (from ISP) and then a Belkin G wireless router (model: F5D7234-4 V4).
I have three rigs hooked to the router (LAN) and run my laptop wireless (all crunching rigs). Again - I am a noob in regards to networking and would appreciate any help

EDIT: So I found this setp feature "Firewall > DMZ" and was wondering if it would be worth a try or if it is to dangerous to leave my gaming rig unprotected: "The computer in the DMZ is not protected from hacker attacks."???



2nd Edit: Well I tried it out and it worked great! CRSYS 2 MP showed NAT:Moderate and I was able to play several mp games with no issues!!!
Just have to remind myself to disable the DMZ when I am done playing

Had you tried portforwarding port 61400 to the IP address of your computer on the router? It's more safe so instead of having all ports open to your computer in the DMZ, it will just be the one. Here's a link on how to do it: http://www.pcwintech.com/port-forwar...elkin-firmware

I will check it out.
