    - 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.
