Some packets re-transmitted as part of a full-proxy, non-SNAT'd TCP virtual server on a translucent-mode vlangroup do not correctly have the translucent-mode bit-flip applied.
Egressing traffic with the source-MAC of another host can potentially lead to traffic loops.
This occurs with a translucent vlangroup and full virtual server with no SNAT.
Enable SNAT on the virtual server.
All TCP re-transmits have the proper source MAC address.
