The translation of 2.3.4.5 is set to 3.4.5.6. If I set it to 1.2.3.4, then it just points to itself and there is no traffic to 3.4.5.6. According to the docs:

 

An inbound SNAT translates the original client source IP address in a request to a BIG-IP system virtual server or BIG-IP system self IP address, forcing subsequent server response to return directly to Local Traffic Manager. When an inbound SNAT is configured on the system, Local Traffic Manager translates not only the destination IP address in the request (using the standard address translation mechanism), but also the source IP address in the request (using a SNAT).

 

Client/source 1.2.3.4 sends request to 2.3.4.5 on BigIP. BigIP changes source ip to 2.3.4.5 then sends request to server 3.4.5.6. Is that how you read it? If so, how would I configure it? iRule SNAT? Virtual Server?
