Private VLAN and VLAN Group Problem !!!

Hi

We have a topology on attached. Using private vlan configuration. Config is working but not quite. Example working 1 minute after don't work 2 minute. Private vlan id 100 and community vlan id 1002 created vlan grup. Only tag vlan 1002 f5 access node but f5 not access firewall. Just the opposite only tag vlan 100 f5 access firewall but not access node. Only working vlan id 100 and 1002 vlan group but not quite. Also ping on firewall to F5 local self ip's firewall duplicate ip error.Self ip's not used everywhere. Where is problem can be?

Thanks.
