Ping is a powerful test tool in diagnosing connection problems.
In these circumstances, it can be useful to know if a Safepipe received a ping request, even if the ping response didn't get back to you. To achieve this you need to create a logging rule in the Safepipe firewall. Enter a sensible Comment, select the ICMP protocol and select 'Coming from' and 'Any' interface. Check the 'Enable' and 'Log' options. Click 'Apply Changes'.
