Use Traffic Rules as a next-generation Firewall that is capable of advanced security filtering to Block, Allow, or Speed Limit specific traffic.

Common use cases for Traffic Rules are:

  • Parental Controls: Block specific apps / websites at specific times.
  • Speed Limit: Set download and upload limits for specific clients.
  • Domain Filtering: Prevent clients from accessing specific domains.
  • Network Isolation: Prevent clients on different LAN networks from communicating with each other.

Requirements

Available Options

Traffic Rules can be configured to:

  • Block, Allow or Speed Limit traffic.
  • Match an entire LAN network or a specific client device.

  • Be always active or on a schedule.

Specific traffic can match on the following categories:

  • App
