NTOPNG & XBOX High Packet Loss Error

[jimmer]

Hi.

After a day of troubleshooting I am at a loss.  Here is the problem and what I have learned so far as a "root cause" although I am not satisfied yet with keeping NTOPNG turned off as the solution.

When I have NTOPNG running on my OPNSENSE firewall, my XBOXONE experiences high packet loss preventing online multiplayer gaming - although it does say its connect to the Internet.  No other services seems to be impacted

When I turn off NTOPNG, my XBOXONE has no issues.

My OPNSENSE FW is set up to support NAT OUTBOUND for my XBOXONE with the appropriate ports being openned for the XBOXONE only.

Has anyone else run across this issue?
