Hi, I'm trying to better understand the rulebase on our Sidewinders and can see a number of rules that source NAT field set to "Firewall (IP)" which a mouse-hover shows as 127.0.0.1. I'm trying to understand in what scenarios you'd want to set the source address of a flow to 127.0.0.1. All I've come up with is a way to prevent the traffic from being forwarded...... Any advise much appreciated!!
Typically you would want the source NAT set to "<localhost> (Host)", which automatically NATs to the outgoing interface. Can you tell what the traffic is actually being NATted to when using "Firewall (IP)"? If it is indeed NATting to 127.0.0.1 then I would expect that to fail.
