I got a WNR3500L recently and flashed it with tomato USB.
Now i have the problem that my xbox 360 reports a moderate NAT in the connection settings. I have all the relevant ports open and forwarded to the correct ip adress.
The only way i am able to get my 360 to report an open NAT is to enable UPNP. If i go into the list of opened ports i see that port 3074 has been opened, the very same port, same protocol, to the same ip, that i manually opened. I'd rather not have UPNP enabled unless it is really necessary. My old WRT54gl with tomato firmware never gave me any problems.
any ideas what could be causing this?
I tried assigning the console a different ip, deleting and adding the ports again, turning off the tomato firewall and the nat helpers but that did not work.
