The SBC is using the BIG-IP as it's gateway. It seems logically that traffic out of the SBC passes through the Big-IP, then is SNAT'd. (which does happen). On the return to the Big-IP, we have a VIP with the same ip to take the traffic and load balance it. However, traffic just goes back to one SBC (whichever responded initially, and it sticks to that one) and you never see anythig passing through the VIP.
