So far, we have had the ability to add a load-balancer to a switch. This works fine for east-west traffic. It was assumed (and lightly tested) that it also works for north-south traffic by adding the load_balancer object to the lswitch connected to the local network.
But, in more extensive testing, it was observed that this does not work when we add a SNAT rule to the gateway router. That rule is in a different zone and will intercept traffic heading out the logical topology without any knowledge about the load balancer rule added in a different zone. This fix, lets us add the load_balancer to the gateway router too. It has the added benefit that it works fine with floating IPs for north-south traffic. i.e., floating ips can be load-balanced to logical ips.
