    Is it simply that ICMP echo is not enabled by default on virtual addresses?

     

    Best I think to set up your nodes and pools with monitors, as you'll need them, and see if the F5 is generating the traffic you expect. e.g. get something working above ICMP and ARP level.

    If I may add, if you can see the ARP requests, but the F5 doesn't respond to ping, it's very likely that you have your interfaces wired backwards. Try switching the interfaces in the VLAN configs.
