NAT won't STAY open

I'm fairly accustomed to networking, however i cannot solve the issue i've been having. Upnp has been typically all i needed to open the NAT on my 360, but as of late it switches back to moderate on a daily basis.

I do have a solution: turning upnp off, resetting my modem, and turning upnp back on will open it up...but why won't it stay open?

Hardware: Actiontec R1000H....

ISP: Bell FibreOp

Note: putting my Xbox in the DMZ under a static IP only yields a moderate NAT...does this make it an ISP issue?

I've also tried manually forwarding the ports, with upnp off, to no avail.

Help is appreciated!

Sorry to hear this problem. If your NAT won't remain open for better connection with multiplayer, then yes, this would be chalked up to a Networking issue that would need to be taken up with either the OEM(Original Equipment Manufacturer) of your router; or call your ISP if you have a modem router combo.

However, one of these might help ya out -


Hopefully one of these help you out.
