How to pass other types of server traffic, non load balanced, with LTM

The outbound subnet/path for general server traffic is a different vlan to where the normal client facing virtual servers operate. SNAT makes no difference. I'm trying to duplicate an existing VE, and an existing physical HA pair, into a HA pair of VE, both of which have this working.

I'm seeing no packet counts on either vlan, all counters are zero. HA which uses a diff vlan, but the same interface (tagged interface) is fine. I see L2, I see the mac-addresses across the switching network, I see arp entries (although the server can only ping the self IP(s), not the floating IP???, but on the other HA physcical 4200v pair I can? Clue?), so I have basic network going I thnk.
