Title: Sudden and unexplained connection interruptions (state flushes?)
Post by: drivera on February 11, 2019, 09:05:08 pm

Hi!

I'm experiencing many sudden and unexplained connection interruptions.  Suddenly, and without explanation, the firewall will even reset an SSH connection I have running on it displaying traffic capture over a LAN link!!!

I'm not sure where to begin to offer up log information.  It feels as though the firewall is resetting states periodically. Is there any logging feature that enters a message in the logs when firewall states are reset (and how do I enable it)? Maybe that can be the first step to figuring this out...

Thanks!

I believe this might be related to another issue, as WAN connections for some seem to be dropped every 10-20 minutes:

There is also an issue with an active discussion at github:

That github issue appears to be the same one, so I think I'm good for now with the workaround (don't clear states when IPs change), and will be fine with 19.1.2.

Thanks!
