How to load balance receive connectors and preserve source IP address.

Hi,

So just to sum up your need:

You want to preserve the source IP address so the receive connectors know who it is coming from.

Of course in this case you have to disable SNAT Automap (In this case source address IP will remains the same, so it will not translante with self IP) but it's means that "receive connectors" will respond directly to client withtout passing by F5. This is commonly known as asymmetric routing. In asymmetric routing, reverse network traffic takes a different path from the original flow. this may create a problem !!!

And of course when you activate SNAT AUTOMAP, "receive connectors" will respond to F5 then F5 respond to client. and in this case it will works.

You have only one alternative to meet your needs. You have to disable snat in order to preserve Source IP but in order to force "receive connectors" respond trough F5 to avoid asymmetric routing you have to configure The "receive connectors" default GW to F5 (Floating IP if is a cluster or Self IP if is standalone).

Hope it's clears. Keep me update if you go ahead and if you need more details.
