Circuits

Circuits define physical connections to the WAN/Internet. For appliances with more than one bridge configured, you can bind each bridge to a separate circuit or you can treat all bridges as one combined circuit. Typically, when the appliance is placed in-line, one circuit would be created for each physical link.

When defining circuits, ensure each bridge is bound to a circuit; otherwise network traffic on any bridge that is not bound to a circuit, will not be affected by policy and will be monitored in a catch-all circuit.

Version Info:

  • For version 7.0.2 and earlier: A circuit can only be bound to one bridge, or all bridges (but not greater than 1 bridge and less than all bridges) or one WCCP interface.
  • For version 7.0.2 Update 1 and later: A circuit can be bound to any number of bridges or one WCCP interface.
