I FIX NATS!!POST IT HERE IF YOU HAVE PROBLEMS . GET TEAMVIEWER AND I'll HELP YOU!

Basicly..
If you use a router (I and II are used only for routers)
I.You get NAT becouse your router blocks the gunz port and u have to unlock it.
-You can try to PORT FORWARD. [www.portforward.com]<-This is not advertise.There you have to choose your router model and the game/program you want to portforward.In this case we want to PortForward Gunz.
* This did NOT work for me.I have an Edimax Br 6214 K.
* Portforward.com provides you tips howto portforword gunz on every Router Model.

II. Go to your router main page(mine is: 192.168.2.1) -depends of the model of router- and disable Firewall/NAT. If you can`t disable.. use DMZ HOST.(This unblocks all of your ports)
* Just a side note: A lot of Router Main Pages is 192.168.1.1. Thanks to Hyourinmaru!
* I recommand to use DMZ Host. It does not unblock just gunz ports, it opens all your ports.

How to configure DMZ HOST.
Step 1:Go on Start->Run->cmd-> Ip config.
Step 2:There you will see an Ip Adress( My router provides me:192.168.2.100)*Depends on every Model
Step 3:Go on your router main page(Mine is 192.168.2.1)
Step 4:Log in.
Default is:
User-admin
Password-1234
Step 5:Search for DMZ Host.
Step 6:There put the ip that the router gaves you * Step 1 and Step 2.
Step 7:Tick enable then press apply/ok.Here you are Done.
Step 8:Enjoy playing gunz without getting NAT.

If You connect through a modem/you connect directly to the internet.
III. If you your computer connects directly to the internet(No Modem/Router) and you
get NAT / you find out that your ports are blocked (Ex:Bitcomet) contact your internet provider and tell them to open your ports.

IV.Disable your Firewall.(From windows/Anti-virus.)
