Ping members of the pool
I'm a noob to the F5 Big IP LTM devices we have. I've set up a SharePoint virtual IP to loadbalance connections to two front-end servers. The developer would like to be able to ping from a client workstation and have the ping request reply with the IP address of the member server of the pool, not the virtual IP address the load balancer uses for the pool. He would like this in order to know to which of the two servers the client is connected. He says he's used other balancers that had this enabled, and it would make sense. However, I'm not finding anyone - or not querying sites using the correct terms - that discusses setting this up on a Big-IP LTM. Can anyone assist?
I did get on the iRules forum and set up an iRule that adds the member server IP to a responding HTTP packet, and we can use Wireshark to review a comment in the HTTP heard to find the IP, however it requires an HTTP header utility, or Wireshark on the client. A ping request would be helpful so as not to require an additional software install.
Thanks.
