Firewall dropping packets for standard applications

Hi Community,

I am seeking your advice... I recently upgraded my hardware from an XG105 to and XG115 to address performance issues we were experiencing with MSFT Teams, WebEx, Nintendo Switch, etc.

Given both my wife and I are WFH now due to Covid, our issues have become more apparent.

I am not a network or security engineer, but know enough to navigate my way around the FW. 

If I set up a persistent ping to and external address, say Google's DNS, and run a Team calls concurrently, I will notice the video and audio performance degrades and I see packet loss on the ping.  I also filter the logs by my laptop IP, where I am running Teams from, and can see denied traffic.  When I look at the addresses via a domain lookup (Centralops), most of the addresses are AWS, MSFT (direct) & Azure (Hosting), etc.

I have added exceptions into my rules but this doesnt seem to make a difference.

The last thing I want to do is create a whole bunch of bypass rules and compromise the effectiveness of the FW - whats the point of having it.

So, what is the best way to get support on this?  I need some help in diagnosing the root cause (poor configuration, missing rules or policies, etc).

  • Hi,

    thank you for the screen shot.

    Your single performance looks very much like my FTTC 50/20.

    I don't think your issue is with the firewall rules but more with connection issues.

    Please check the Network tab in the XG GUI to see what each interface is showing. You should be looking for auto-negotiation or full duplex and 1000mb/s.
