Address translation query

Guys,

 

Im trying to understand what exactly happens when address translation is enabled on a VIP. I assumed once enabled it was reading settings from the address translation section on the GUI (NATs, SNATs etc), and applying from there once triggered with matching source IP.

 

Im likely way off with that, as ive never looked into this in any great detail, things have just worked away nicely in background.

 

Basically now i am trying to troubleshoot an issue on a VS, that has address translation tick box enabled, yet the client IP is preserved in the server side connection, and im trying to understand what is preserving client IP.

 

Does address translation tick box preserve the client IP, or is it that something is mis-configured??

 

v11.

 

No automap enabled on VIP.

 

Thanks in advance guys ;)

    the default gateway for the proxy servers is another VIP on the same F5, which load balances to external FWs.... i.e. not the self IP

     

    i think when proxy server initiates a new connection to internet, it will hit firewall virtual server but return traffic (to client) will match existing connection which was created by proxy virtual server (when received traffic from client).
