Checkpoint handling of ping traffic

I am having some trouble getting ping to work over a VPN connection to another party whoose firewall is beyond my control. My understanding of ping is that it is not treated as "stateful" by Checkpoint firewalls hence needs a rule for both "echo-request" traffic in one direction and another rule for the return "echo-reply" traffic. Something like the rules below.

Firewall A
Source X Destination Y echo-request permit
Source Y Destination X echo-reply permit

Firewall B
Source Y Destination X echo-reply permit
Source X Destination Y echo-request permit

I want hosts behind Firewall A to be able to ping hosts behind Firewall B, but not the other way around.

Obviously I cannot enable "accept icmp requests" in global properties.

Is this the "best practices" way for dealing with ping on Checkpoint.

only a single rule is required for ping Checkpoint manages the return connection.
If the Firewall at the other end does not allow ping over the VPN from your end then you will not be able to change this.
