Sorry mate. Formatting goes crazy sometimes when trying to edit your responses.

I guess you could create two VIPs (one TCP, one UDP) which listens to all ports and then drop the requests that does not fit the port span you defined above with an iRule.

Maybe something like this for the tcp VS:

when CLIENT_ACCEPTED { 

    if { ! (([TCP::client_port] > 1570 and [TCP::client_port] < 1575) or ([TCP::client_port] > 2500 and [TCP::client_port] < 3500)) }{ 
        drop
    }
}

Never worked with UDP this way but perhaps the client data event would work:

when CLIENT_DATA { 

    if { ! (([UDP::client_port] > 1570 and [UDP::client_port] < 1575) or ([UDP::client_port] > 2500 and [UDP::client_port] < 3500)) }{ 
        drop
    }
}
