Now that's one of those fundamental basic questions that seem to throw me every now and then. Ignoring the Packet Filter for a moment I'm thinking yes, you're right and actually, the Virtual Server doesn't have to be on the external VLAN, it only needs to be on the VLANs the initiating host can communicate through.

 

 

Can you try and remove the Virtual Server from the external VLANs, do a test and do a tcpdump (all VLANs) and see what happens? That's where we should have started I'd say!
