persistent client-server connections. Recently, we placed the application traffic behind an F5 Load Balancer, and since then, we have been running into session persistence issues. Some clients establish a connection successfully, but when routed through F5, they lose their session state or get disconnected after only a few requests. Without the load balancer in the middle, connections remain stable.

We have tried configuring source IP persistence on F5 Networks, but since many clients connect from behind the same NAT, this hasn’t completely solved the problem. I’m wondering if anyone here has experience using Clever TCP components with F5 in a similar setup. Would cookie-based persistence, TCP connection mirroring, or SSL offloading adjustments work better in this case? Could there also be timeout or keep-alive settings in Clever Components that I should tweak when running behind F5? Any advice, configuration tips, or best practices would be really helpful.
