Simple Round Robin configuration

Being able to connect from an external machine (either on the same subnet or on another subnet) to the IP 192.168.100.160 and being balanced to 161 and 162 alternatively refreshing the browser.unfortunately this isn't a direct answer to your question, but i would say that having the client, the virtual server, and the web servers on the same subnet may cause you problems when testing. when the traffic hits the back end server it's not going to route back out through big ip as the client and the server are on the same subnet (i.e. communication will be over layer 2 rather than layer 3)

 

 

that's my understanding anyway! hope it helps a little
