Xbox NAT help

[HaloCod27]

I have a strict NAT, and can't fix it. I have an Apple Extreme Airport.

I want to get a new router, but my mom doesn't want to mess up our wifi by getting rid of the Airport.

Can I buy another router and have both of them work in my house? Will it cost more a month or something? Also, what are some cheap routers that will get me an open NAT

I used to have the same problem, this is what i did to solve it:

*Under DHCP Reservations: Reserve an IP address for your Xbox using it's MAC address.

*Then, in Port settings, apply the following:

*Finally, go to you network setting in your xbox and assign the reserve IP with subnet and default gateway.
