Persistence issues when using two different Virtual servers for the same traffic

​So I a currently have it setup like you said. But it seems like the traffic is encrypted from virtual server A to virtual server B. I did look at X-forward-for but I thought this just adds the client source IP to the header and doesn't affect source address persistence.

Can anyone confirm that x-forward-for would affect source ip persistence when load balancing traffic to pool members or does it use the internal float ip of the first F5 virtual server?
