Gateway ICMP has a special purpose.

A Gateway ICMP type of monitor has a special purpose. You use this monitor for a pool that implements gateway failsafe for high availability.

A Gateway ICMP monitor functions the same way as an ICMP monitor, except that you can apply a Gateway ICMP monitor to a pool member. (Remember that you can apply an ICMP monitor to a node only and not a pool member.)
