Confusion on SNAT and source IP/Ports

Network > Routes tab to add the routes.

 

 

To get the client IP, you need to set up a virtual forwarder on the LTM, and use it as a gateway, or do the second NIC as described. I don't personally like that solution too much.

 

 

Alternatively, if this is a Web App, you can insert X-Forwarded-For headers and set up IIS to pick that up. Easiest solution by far.
