I am unable to remote ping (ICMP ping) Archer AX73 (AX5400) via WAN IP to remotely check internet status. I have updated to the latest firmware and in the router settings I have the setting enabled: Advanced->Security->Firewall->Responds to Pings from WAN.

I do not have this issue when using another router and the same wan ip so definitely seems to be the router itself not responding to the remote incoming pings.

I have dynamic IP, DHCP enabled, NAT enabled, no forwarded ports. I can ping the WAN IP (ISP IP) via the router diagnostics page and get a response but not from any remote machine/server.
