Virtual Server to maintain the same destination port to the backend

- You can also keep port translation enabled if traffic destined on VIP port should be sent to same port on the pool member. This should work.

​

- You would need VIP defined on any port. Configure iRule​ to only allow specific range and discard traffic for other ports.

​

Please modify accordingly for start and end port range​

when CLIENT_ACCEPTED {    
    if {([TCP::local_port] >= <start port>  && [TCP::local_port] <= <end port> ) } {
       return   )
    else reject
}

​- define pool with all 4 members and any port.
