If anyone is interested in this I found the problem. I needed to enable promiscuous support for the vswitch in esxi.

 

 

Use of VLAN groups (CR137596)

 

Use of VLAN groups with BIG-IP Local Traffic Manager VE requires proper configuration of VMware vSwitch or VMware vSwitch portgroup security policies. The Promiscuous Mode and Forged Transmits properties must be set to Accept. By default, Promiscuous Mode is set to Reject. For information on how to configure these options, refer to the vSwitch sections of VMware's vSphere manuals.
