Solution
By default, FortiGate does not pass layer-2 traffic.
If there are layer-2 protocols, configure FortiGate interfaces to pass these protocols without blocking.
Configure it via CLI:
# config system interface
edit <<IPsec VPN interface name>>
set arpforward enable
set broadcast-forward enable
set netbios-forward enable
end
The connection between the two clients confirmed that the ICMP is passing through.
