You can configure a VIP on port 0 (any port) and then use an iRule or IP filters to restrict which destination ports can be used. Here is an example iRule which drops requests outside of a range of ports: 

 
 when CLIENT_ACCEPTED { 
  
     Check if requested port is outside 1000 - 2000

        Drop request 
       drop 
    } 
 }
