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.

Please check your IPS settings. If you enable the "Low priority attack" PING will get block.
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?
Thanks for your reply, the server is external eg. www.yahoo.com. 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 22.214.171.124, 126.96.36.199, ...etc. I have checked thru the firewall policy and cannot find any problem that the ICMP traffic has no reply echo.
Hi AJISHLAL / SHIPRASAH,
Thank you so much for your advise, after clear the low priority check I'm now able to ping and trancert at the PC.
Glad we could help. Have a good one!
