This is a simple guide for restricting bandwidth usage of a single IP address on pfSense 2.2. Start by logging into the pfSense admin panel.

Create the Limiters¶

• Open Firewall -> Traffic Shaper -> Limiter.

• Select Create new limiter.

• Create the first limiter named uploadThrottle.
  • Click Enable limiter and its children .
  • Enter Name uploadThrottle.
  • In the bandwidth section, click on the [+] and enter 5, and set Bw type to Kbit/s
  • In the Mask section, use pull-down menu and select Source addresses and the IPV4 mask bits enter 32.
  • Enter a Description
  • Click Save

• Create the second limiter named downloadThrottle.
  • Click Enable limiter and its children .
  • Enter Name downloadThrottle.
  • In the bandwidth section, click on the [+] and enter 28, and set Bw type to Kbit/s
  • In the Mask section, use pull-down menu and select Source addresses and the IPV4 mask bits enter 32.
  • Enter a Description
  • Click Save

NOTE: This will effectively create a limiter with the speed equivalent to a dialup connection. Adjust accordingly

Setup The Firewall Rule¶

  • In the Source Type pull-down menu select Single host or alias
  • In the Source Address enter the IP Address of the host being throttled.
