How do i drop packets selectively(to certain destinations) from my freebsd gateway?can the ipfiltering tools be used? its important to note that i will be filtering packets only when i detect congestion.as soon as congestion is under reasonable control i intend to stop my filtering.what would be the best approach?what tools should i use?
