Directing Traffic with Policy Routing¶
Policy routing in pfSense® software refers to the capability of routing traffic by matching it to specific firewall rules. This is primary used for multi-WAN, though it has other uses as well.
Each firewall rule allows for the selection of a gateway. If none is selected, traffic goes out the default gateway or follows the routing table. If additional WAN interfaces or gateway groups are defined, these may be selected in the Gateway field when adding or editing rules to direct matching traffic as desired.
For more information, refer to the Policy Routing Configuration section of The pfSense Book.
