LTM persistence with a SNAT pool

Thanks for the quick reply.

 

 

Maybe I am worrying for nothing..

 

 

To further explain..

 

 

Client comes in with an IP of 1.2.3.4 and get load-balanced to server A.

 

 

The packet gets SNAT'd on the way out to 10.1.1.1 and server A sees the connection come from 10.1.1.1

 

 

Client then clicks on a link and another packet comes in to the VIP with source IP of 1.2.3.4 but gets SNAT'd to 10.1.1.2

 

 

So will it go back to server A with source_IP persistence set up? or will server A think it's a different connection because the IP is changed?

 

 

But the LTM is creating the persistence record before the packet leaves then I should be ok.

 

 

Thanks for your help.
