PCI 3.0 Compliance with LTM

Hi people,

I have a mission to deploy a F5 LTM/ASM (in a future GTM) in a PCI 3.0 environment and it kills me because we need to balance external connections and inter-vlan traffic, no problem with that in a simple environment, but PCI requests that every traffic on VLANs is checked by an IPS.

So, my insights until now:

From WAN: Internet -> External (1 Route Domain/ASM/LTM) -> NGFW (FW/IPS) -> Internal partition (4 Route Domains/LTM) -> Servers

Inter-Vlan: VLAN1 Server -> Internal partition (VLAN1 Route Domain) -> NGFW -> Internal partition (VLAN2 Route Domain) -> VLAN2 Server

Please any one already face this situation? Any thoughts about this scenario? Any tip on how improve this? Should i change this deployment based on Partitions and Route Domains to work with isolated Guests?

Thanks for the help!
