I keep getting disconnected from my xbox live, I think it's because of my nat being strict but i've trid port forwarding and other things like setting the default server to my xbox ip but no joy. It was fine b4 but last week or so i keep getting disconnected. anyone else having the same problem?

Put the Xbox 360 into the DMZ on your router, that always solves NAT problems for me.

I have a zyxel 660, how do I do that?

Dunno,

Access the modem and set up an IP address as the DMZ zone and then set the Xbox360 to that I would guess.

Sorry but I don't see a dmz zone in my router

You can also disable the firewall of your router and enable UPnP

It's back to normal again, I messed around a bit turned router on and off now it's ok. Cheers
