Firewall Rule Not Working

Hi guys, I'm having a bit of a weird issue where machines in one of our subnets are unable to ping machines in another local subnet. I have configured a firewall rule allowing any service between the two subnets, but even then pings aren't working. I've been told it's worked before but I can't confirm that as nothing appears in the logs. Even when I ping nothing comes up in the firewall (Check Point) logs.

The machine we're trying to ping to is a Linux one managed by our external supplier. I have asked whether there are any iptable rules being applied that will drop the pings but apart from that I've no idea where to start. Any advice would be hugely appreciated.
