In pfsense, the most commonly used to control the network speed limit is the "limiter" in the flow ×××, you can understand it as a pipeline, 10Mit/s download pipeline, then the maximum download flow will not exceed 10Mit/ s. The flow limiter combines IP, network, and alias to set different speed limit rules to meet the needs of network management.
In this tutorial, the network speed setting is divided into three situations. They are single IP, network, and alias.

1. Set the download and upload "limiter"
Two, add firewall policy
1. The traffic speed limit is finally implemented under the firewall strategy. Suppose I want to limit the rate on the lan port, then enter the firewall rules of the lan port for configuration.
2. Click the advanced configuration button and scroll down.
3. Add the previously set upload and download limiters respectively, and save it.
Three, use source and destination IP to restrict
Add a single address or address segment that needs to be restricted to the source and destination addresses in the firewall policy
Fourth, limit the speed of the entire network port
1. Limit the rate of lan port network address traffic
Five, use aliases to restrict
1. Add an alias, and divide the hosts that need to restrict traffic into an alias group.
2. Add the alias group to the firewall policy
