Frontier Communications → [DSL] Xbox 360 moderate nat

I have a westell A90-750045-07 router how do i open my nat.

You should try the static nat or dmz host option

I dont know how to do that :/

Here's the static nat setup page url
192.168.1.1/htmlV/fw_static_nat.asp?

Here's the dmz host setup page url
192.168.1.1/htmlV/fw_dmz_hosting.asp

The ps3 needs to be a dhcp client for both options, after setting up a option you must reboot the ps3

Also is turbo tcp good to have enabled?

turbo tcp can make file sharing less troublesome
