CHAPTER 21
Policy Forwarding
21.1 Overview
Traditionally, routing is based on the destination address only and the Zyxel Device takes the shortest
path to forward a packet. Policy forwarding allows the Zyxel Device to override the default routing
behavior and alter the packet forwarding based on the policy defined by the network administrator.
Policy-based routing is applied to outgoing packets, prior to the normal routing.
You can use source-based policy forwarding to direct traffic from different users through different
connections or distribute traffic among multiple paths for load sharing.
21.2 The Policy Forwarding Screen
The Policy Forwarding screens let you view and configure routing policies on the Zyxel Device. Click
Advanced > Policy Forwarding to open the Policy Forwarding screen.
