Load Balancing inquiry regarding single server response

Hi All,

I have a LTM, VS is 10.10.10.1 and pool server of 172.16.20.111 and 172.16.20.112 which uses 300 different tcp ports but i configured it ANY, i have VS wildcard(SNAT AUto-map) for connection of server pool to external vlan.

I have client 10.10.10.5, when i initiate connection to vs(10.10.10.1), no problem.

Here's the problem, client wants to open all 300 ports, for example port 9999

from 172.16.20.111 and 172.16.20.112, initiate traffic to 10.10.10.5, in our lab, they use "telnet 10.10.10.5", now when 10.10.10.5 sends traffic using port 9999 , both 172.16.20.111 and .112 receives the traffic, client wants only one server will receive it. Is there a way?
