VS and Pool Members with multiple ports

In previous experience you would configure a virtual server per port if it's limited to a small amount of ports such as what you have provided. You would then configure a pool per port and associate that pool to the virtual server. You can have the same IP with different ports in the same pool but not a range of ports. If you wanted to allow the F5 to balance the entire range of UDP ports you could configure a VS listening only on that IP, UDP, and no port. You can then configure an iRule to a pool selection based on the port that was hit on the virtual server. I don't recommend doing it this way because it complicates things when you could keep it simple and just configure a VS and pool for each port you would like to use.

create 11 vservers.
1 for each udp port.

you only need to create 1 pool.
put all 33 servers into it then bind the pool to 11 vserver above.

pool member doesnt need to be same port as the vserver because f5 vservers does L4 proxy.
