The client's destination IP (the virtual server IP if it's a host virtual instead of a network virtual) can only be retrieved using IP::local_addr in the clientside context. To get the client or server IP addresses, Michael's suggestion makes sense.
here IP::local_addr] equals gol_networks -- means destination in the pkts coming to LTM
That's correct.
See your earlier post for a link to a thread with more detail on clientside versus serverside context:
