I work at a university with on-campus housing. I have been some complaints from students that they are not able to play online multi-player games using their XBOX. Not an extreme concern for me, but trying to understand what is happening. Most of the students get an error "NAT Type: Strict and UPnP not successful"
We are full stack Meraki environment, MX450>MS250>MR33. On the MX450 for the student housing buildings, there are NO outbound firewall rules, completely wide-open! Not sure why some, not all, of the XBOX consoles are getting this error. Haven't received any complaints from any using another games console, i.e., PS4 or PS5.
