kridsana,

 

whether a virtual address has ARP/ICMP echo enabled does not impact the monitoring of that the server. This is purely determined by the health monitor on the node. Saying that, a host forwarding ip virtual server does not have a concept of a pool so won't use this to determine whether the backend server is up. It simply forwards the traffic regardless.

 

Hope this helps,
