A couple of things I'd look at:
-
Firewall issues? You may see some data in statistics, but it may not be the traffic coming form an external client. Test with a tcpdump capture to makes sure you're actually seeing this traffic at the front door.
tcpdump -lnni 0.0 port 20543
-
SNAT issues? If you see the traffic coming to the VIP, and you also see traffic going to the pool member, look at the source address in the data flowing to the pool member. Is the client's true source? If so, does the server have a route out that it will attempt without going back through the F5? Apply a simple SNAT Automap profile to the virtual server and see what that does. You should see the F5's self-IP address as the source address going to the pool member.

Internal routing? Does the F5 have a route to the pool members? Can you ping them from the F5's management shell?
