Having trouble with destination based SNAT irule

In the context of this iRule and these connections I would expect remote_addr to return the IP of the server (identical to client_addr in the clientside context) and local_addr to return the self IP of BigIP in the vlan where the server lives (unless I misunderstood how local_addr should work).

 

I was thinking that [IP::server_addr], which is the same as [serverside {IP::remote_addr}], might be what you're looking for. You're interested in getting the destination address, and the three options you have tried are all in the clientside context.

 

 

The part that boggles me is: and it retains its private addressing

 

I would expect that if the server initiating this connection has a local address the first piece would always execute when using [IP::client_addr] or [IP::remote_addr] rather than the other way around.
