Corporal Pike,

 

To do this you will need to create two new monitors, one for server 3 and one for server 4. Create the monitor as you would normally but set the Alias Address to the IP address of server 3 for one monitor, and server 4 for the other.

 

Then in your pool with server 1 and 2 you would need to configure the monitors on the individual pool members, rather than at the group level. For example, for server 1 add the existing HTTPS monitor and the monitor with Alias Address for server 3. Set the minimum available monitors to 2. That way both monitors need to come up to mark server 1 up. If server 3 went down it would mark down server 1 from the pool.

 

Hope this helps,
