How do we preserve the source ip in udp request and forward the same to backend pool?
I can see that the LB ip in the request when the request comes to pool member but I want to keep the source IP when F5 forwarding the request to pool.
Don't set any address translation (no SNAT or SNAT Automap) on the UDP virtual server.
It's best to use a Performance Layer 4 virtual with Loose Init/Loose Close.
However, the pool member has to be able to respond directly to the source IP, or use the BIG-IP as the default Gateway.
