It sounds like this might be a (temporary) service issue with Xbox Live per the previous response. However, we were the school that reported the game console NAT issues with our Palo Alto last winter. Our interim solution for spring semester was a very labor intensive 1:1 NAT solution with reserved IP addresses. Our solution for this school year is that as we have implemented Cisco ISE, the system is able to auto-profile game consoles and put them on a VLAN that uses public IP addresses while other devices on the network are assigned private IP's and NAT'd. We just went live at the beginning of August and so far, so good.

Getting information passed on to us can be difficult but with more information and some testing, the problem appears to only affect Xbox 360 (not Xbox 1) and only happens when more than one user tries to connect from the same dorm network. We are using PAT for each of our dorm networks, and the Microsoft answer is to open up ports on the firewall. But since we use PAT, we would still have to go to a 1:1 NAT before we could do any port forwarding. There was a discussion on similar NAT issues with Xbox early this year (January) on this list relative to using Palo Alto firewalls thus I thought I would try this list again. Right now, we are wondering why this problem just started occurring this semester as we haven't had problems in past years using PAT. The fact that it only affects the older Xboxes would indicate the issue is on Microsoft's side. Is anyone else seeing this problem? And how are you dealing with it? The only fix I see so far would be tracking the hundreds of Xboxes on campus and assigning them static or reserved IPs with a 1:1 NAT which seems to be impractical and time consuming. __ David Councill Network Security Engineer Washington State University Information Technology Building | PO Box 641222 | Pullman, WA 99164 david.councill () wsu edu
