It would help to capture a tcpdump of the client connecting directly to the server and compare that with a tcpdump on the BIG-IP through the VIP. For the BIG-IP, you can use syntax like this to capture traffic on all interfaces involving the client or server IP's:
tcpdump -i 0.0 -s0 -w/var/tmp/trace.dmp host CLIENT_IP or host SERVER_IP
Replace CLIENT_IP and SERVER_IP with the actual addresses. The output is written to /var/tmp/trace.dmp or whatever you name the output file. You can use Wireshark to view the trace. If you get stuck, F5 Support can help you review the tcpdumps.
