Firewall drops traffic from internal network

AWP

The UTM firewall just drops connections or disconnects itself from internal network, while we are able to access the firewall from external network side, at the same time internally their is no problem, connectivity between the internal network is normal. It happens randomly and may once in week, sometimes once in a month or 3. In all the cases restarting the firewall resolves the issue.

    Hi ,

    Thanks for reaching out, and welcome to the Sophos Community!

    Have you noticed a spike in resource utilization during the time of the issue? Are you able to ping the internal interface of the firewall? If yes, are you able to ping an external network with an IP address and with hostname? 

    Are there any interface level packet drops on the internal interface? You can check this by running  "ifconfig" from the CLI. 

    Thanks,
