Hey, quick backstory -- I have little to no networking experience or understanding. I work for a small business that deployed the XG Firewall some years ago when a certified network tech was still working for the company. He has since left without finding a replacement so I am filling the gap and learning networking any way I can. We are a volunteer-based non-profit with no financial room to hire a full-time or even part-time network tech.
That being said, our Firewall covers our office spaces and dormitories and is not allowing parts of traffic through for most online games and most platforms, BUT only on certain Access Points.
Main Issues: In one building, Modern Warfare 2 will not download on my windows laptop. The empty progress bar states "Waiting on another update". However, if I move to another building about 200 feet away and switch over to that access point the game will download just fine. THEN WE SWITCH IT AROUND. A friend tries to go to the access point that worked for me to download modern warfare 2 on his playstation, however on 10/11 of our access points all playstation games hit a wall when downloading.
and the best part of that example is that all of those games play fine if they are already updated.
Games and Devices that don't work: playstation, xbox, blizzard games (hearthstone, WoW), Modern Warfare 2, Black Ops 4, Fortnite (on all devices everywhere including mobile).
All games and devices quote the same general error code mentioned in the Subject, "Requested Range Not Satisfiable"
A note on the Fortnite issue, I can download, update, install, and enter the game with no issue. I am unable to join any matches. However, on mobile if you join a match on data then after you're in the match you switch back to the wifi access point the game will run perfectly.
What I need is I need help deciding if the firewall is the issue, if it is how do I look at the event logs to see what went wrong, how to even read what I see on the logs, then how to implement exceptions or rules allowing these services to do their thing. We use the Ubiquiti UniFi controller to manage our network so keep that in mind if you don't think it's an issue with Sophos.
