Configure SonicWall to allow ICMP traffic

Dear support

The ICMP traffic is blocked in sonicwall to external IP. How do I configure to allow ICMP traffic to ping external IP and get a png echo request at the PC.

    By default ping from LAN to WAN is allowed on Sonicwall. If the server you are trying to ping does not accept ICMP or ping requests it will not work for you. For this, is the traffic coming to the Sonicwall or getting out of the Sonicwall to an external server?

    Hi Dbeato

    Thanks for your reply, the server is external eg. I have no problem reaching the yahoo website or other websites. The problem is that the ICMP traffic is dropped at the sonicwall firewall and thus not able to ping external IP like,, ...etc. I have checked thru the firewall policy and cannot find any problem that the ICMP traffic has no reply echo.
