This question has already been asked, and I carefully read the answers to it.
https://community.checkpoint.com/t5/General-Topics/Cannot-ping-remote-VPN-gateway/td-p/20797.
Setting "Accept ICMP requests" -> "First" in the Global Properties causes ping to the external interface to work, but it is not possible to ping the hosts behind the gateway. If you put "Before Last", then we get the opposite picture.
In another answer it was written that I need to prescribe rules for ping. Can you give an example of these rules? I tried several variants of the rules, but did not achieve a positive result.
Is it generally possible to ping the external interface of the gateway and the hosts behind it?
