Match Across Services irule on wildcard VS

Good afternoon,

I have been digging through the forums trying to find more examples of an irule that can match across services with a VS/Pool using */0. I need to match 4 ports, the customer does not want 4 VS/Pools to accomplish this.

I'm trying to build off this little example, but I am unsure of the right cmds to direct all 4 ports, if seen, to the same pool member. I do not want it to discard

when CLIENT_ACCEPTED { if { [TCP::local_port] >= 18620 and [TCP::local_port] <= 18623 } { persist sticky [1800] use pool my_pool

    }
}

    I forgot the else portion, but I'm unsure this would actually match across ports. The incoming client should be directed to the same pool member regardless. Does a sticky persistence setting on the pool do this even when wildcard? Maybe I'm making it too complicated.

    when CLIENT_ACCEPTED { if { [TCP::local_port] >= 18620 and [TCP::local_port] <= 18623 } { persist sticky [1800] use pool my_pool

        }
    else {
    pool my_pool
}
