The previous recipe used the pfSense traffic-shaping wizard to prioritize Skype traffic and deprioritize BitTorrent traffic. Running the wizard essentially created the traffic-shaping queues as well as the floating rules. Once we have run the wizard, we have a second option for traffic-shaping: manually adding floating rules.
Completing this recipe requires having completed the previous recipe, Configuring traffic shaping using the traffic-shaping wizard recipe, or having run the wizard previously. Doing so will ensure the traffic shaping queues have been created.
EchoLink is a program that allows amateur radio operators to communicate over a VoIP connection. It uses UDP on ports
5199, and uses TCP on port
6000. In order to prioritize EchoLink traffic, we will create two rules (one for UDP traffic and the other for TCP traffic).
