trouble with nat

No. Unfortunately, your Motorola CPEi 25150 WiMax 4G "modem" is also a router, which means that you have a classic double NAT situation (router behind a router) that prevents Open NAT unless very specifically configured. (You can verify this by looking
at the WAN IP reported by the Netgear--it is likely a private class IP such as 192.168.x.x). You can poke around the modem's web interface to see what settings it allows you to configure; but unfortunately from what I can find, unless something has changed,
that modem on Clear lacks the necessary settings to allow you to disable its routing (disable NAT, disable DHCP server, place in bridge-only mode) to allow you to use it strictly as a modem with the Netgear as the only router (thus, eliminating double NAT).
If that is the case, you have a few options. 1) IF the Motorola allows port forwarding (appears it might) or properly supports UPnP, you should be able to use it as the only router and disable the Netgear's routing (disable its DHCP server, connect the Motorola
to a LAN port on the Netgear, NOT the WAN port). OR 2) If the Motorola lets you assign a DMZ (appears it might), putting the IP of the Netgear there may allow its port forwarding to work. OR 3) Replace the Netgear with a simple switch (presuming the reason
you have the Netgear is for additional ethernet ports), and use the Motorola as the only router and wireless access point. OR 4) See if you can get a new modem that is strictly a modem or can be put into bridge-only mode (disables routing, NAT, DHCP server).

Here's additional information that may help explain what is going on:

Would changing the Advertisement Period and Advertisement TTL on the UPNP work? I read somewhere that changing the Advertisement Period to 2 minutes, and the Advertisement TTL to 10 would fix it. I just want make sure that my internet won't be to totally
messed up if I do that.

The 360 is plugged in to the netgear and the X1 is off its wifi. The default password motorola doesn't work which probably means I already have a password and I will have to go find it. I'll look for it tomorrow.

Then why does it let my 360 open? Also, how do I access the Motorola? I think I might've before using an ip that the whatsmyip website gave me, but it asked for a username and password that I have no clue to what it might be. The normal admin/password login
that I use for the netgear doesn't work.
