Ping problem in local network

Hello Benoit,

Good day and thanks for reaching out to Sophos Community and hope you are well. 

May we check if you are still encountering this issue? Did you happen to check the Zone where your APX is configured to?

Many Thanks for your time and patience and thank you for choosing Sophos

Cheers,

Hello Benoit Biernaux ,

Thank you for reaching out to the community, additionally can you also confirm when you initiate the ping traffic, does it even reach the FW ?
Let us know the packet capture, you'll be able to determine the traffic flow - Monitor traffic using Packet Capture Utility
