NAT Always Strict

I can't join some people's parties, I can't join some games - its so half assed.
I have all the ports open for XBL and even have DMZ enabled. Upnp is enabled also.

I cannot fix this problem.
I have my 360 connected to my computer which is then bridged with my router connection. No firewall is running to block it.

Now it's magically open again! It loves to switch between strict, open, and moderate. Sooner or later I'll be back at strict for no reason.

Go into the router

you see the dmz settings?

enable it

go into your xbox find the ip addy and put in the last 3 numbers of the ip addy into dmz

restart xbox and nat should be open always
if it happens again check all the settings to see if they are correct then, turn off your xbox, router and modem for 30 secs, it should work

If IWNet is anything like Xbox Live's NAT ...detector (right word?)... when you use upnp its best to just use DHCP instead of a static IP. With a static IP I'd always get strict but after turning it off it said open. Made no sense but I've been going along with it for quite awhile now and I've never seen it go back to strict.

The results will vary, yes, however that usually fixes it for people with moderate-strict NAT even though it's set up perfectly.

From another post I made. Works for a lot of people but I have no idea why. I'm also pretty sure that having both DMZ and UPNP on at the same time can cause some conflicts... however I don't think that's really related to this situation.

Edit: Would also like to mention, it sped up my matchmaking like you wouldn't believe. Before it would take like 5mins to find a match (always 1/50). After... it finds 17+ and only takes 20seconds to find a match.

You might also have to forward some ports to make it open all the time.
Here are the ports that need to be opened to get it to work right.

tcp 80
udp 88
udp/tcp 3074
udp/tcp 53

After you open those it should let you have an open NAT at all times.
