Xbox 360 NAT (Need it "open") (in Off-topic)

I know the ports i need to forward and I'm on the Port Range Forwarding page on my router UI but dont know what category to put the numbers in. (Application, Start, End, IP Address)

88 - UDP
3074 - TCP/UDP
80 - TCP
2302,2303 - UDP
Enter the ip address of the x-box here i.e 192.168.1.10

These are the complete instructions that are given, if anyone cant help because i have no idea where I'm going in the xbox to do this either, lol.

Instructions:

Well , you can set a static ip address on the x-box...
ip add : 192.168.1.10
subnet mask : 255.255.255.0
default gateay : 192.168.1.1

Check the DNS address under the "status" tab of the router and enter the same DNS on the x-box....

Now on the router web ui , you can either go for "port forwarding" or "dmz"...if you select "port forwarding" you need to forward the following ports ..

88 - UDP
3074 - TCP/UDP
80 - TCP
2302,2303 - UDP
Enter the ip address of the x-box here i.e 192.168.1.10

And if you select "dmz" , type the ip add 192.168.1.10 and enable it....this will open all the ports for the x-box....however, then the x-box will get opened to the internet.....
