Virtual Server - Type Forwarding IP

However they would like to stay with the virtual server connections open only when the connection between the F5 and servers were connected. There is a possibility in the forwarding mode Ip monitor connections and starting the virtual server that you have open or closed ports?

do you mean customer wants virtual server to be active only when server port is opened?

if yes, can you use performance layer 4 virtual server (instead of ip forwarding virtual server) and use server as a pool? on the pool, you assign health monitor to check the server port.
