The feature to use in this scenario is a parameter in the monitor called "Transparent". This is used in combination with specifying an Alias Address and Alias Service under Advanced properties so that you specify an end destination out on the Internet. What Transparent does is that the monitor will be sent to the Alias Address and port but the destination MAC will be the MAC address of each pool member. So the BIG-IP will try to reach the end destination through each router.

 

It might be a good idea to specify a couple of these monitors with different end destinations and set the Availability Requirement on the pool to be at least one monitor, in case any of the servers that you define as Alias Address and Port becomes unavailable.
