If you're doing a tcpdump and not seeing any traffic that means the traffic is either arriving on the wrong VLAN or it's not arriving at the BigIP at all. I would check the former by running:

 

tcpdump -i 0.0 host

 

where is the IP address of your virtual server. If the traffic is showing up on the wrong VLAN or failing to make it to the BigIP at all, then the problem is very likely not with the BigIP but with an upstream switch, router, or firewall. I would start there.
