Policy Route
By default, the Zyxel Device routes packets based on the shortest path to the destination address. Policy routes allow you to override the default behavior and route packets based on other criteria, such as the source address. For example, you can use policy-based routing to direct traffic from specific users through specific connections or distribute traffic across multiple paths for load sharing. Policy-based routing is applied to outgoing packets before the default routing rules are applied.
The Policy Route screen let you view and configure routing policies on the Zyxel Device. Click Network Setting > Routing > Policy Route to open the following screen.
