NimbostratusAutomap/SNAT when servers are on a different internal VLAN and VS's are on an external VLAN
We deliberately place servers to be load balanced on an internal VLAN and VS's on an external. More and more frequently I have having to setup AutoMap or an SNAT pool because servers on the internal network want to use services provided by a different VS than the one they are on.
We also use iApps to try and get some level of consistency. To setup automap or SNAT you have to lie to the iApp and say the servers are a different network than they really are. Or you can write an iRule to SNAT the packet based on source and destination, but that's not something I tried yet.
What are others doing when the situation presents itself? Thanks in advance.

Hello,
When you configure automap on your VS, the source IP is translated by the best matching self ip floating or physical, there is an article that talk about precedence: https://support.f5.com/kb/en-us/solutions/public/7000/300/sol7336.html?sr=53737667
Regarding tbe ways to configure,I think you have one more using ltm policies.
