how f5 deals with ephemeral ports
Hello
I have a question how f5 deals with ephemeral ports ? i have a application ( not external facing) , where client X need to connect server A, B & C. initially client X will connect on port 2551 after getting request server A,B or C will internally open ports 2600-2700 and further communication between client and server will be on one of port from this range (shown in dotted line). i am looking for option to place a F5 LB in between client X and server A B C. is it possible ? what configuration will need on F5 to allow this port range ?

Hi,
You can create a virtual server listening on any port and then use an irule to drop or reject traffic destined to port outside the range.
Look at this dc post.
Cheers,
Kees
