IP Routing Policy Setup
Use this menu to look at and configure policy routes.
36.1 Policy Route
Traditionally, routing is based on the destination address only and the ZyXEL Device takes the
shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism 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 incoming packets on a per interface
basis, prior to the normal routing.
36.2 Benefits
• Source-Based Routing – Network administrators can use policy-based routing to direct
traffic from different users through different connections.
• Bandwidth Shaping – Organizations can allocate bandwidth to traffic that matches the
routing policy and prioritize traffic.
• Cost Savings – IPPR allows organizations to distribute interactive traffic on high-
bandwidth, high-cost paths while using low-cost paths for batch traffic.
• Load Sharing – Network administrators can use IPPR to distribute traffic among multiple
paths.
• NAT - The ZyXEL Device performs NAT by default for traffic going to or from the
ge1
interface. Routing policy’s SNAT allows network administrators to have traffic received
on a specified interface use a specified IP address as the source IP address.
36.3 Routing Policy
Individual routing policies are used as part of the overall IPPR process. A policy defines the
matching criteria and the action to take when a packet meets the criteria. The action is taken
only when all the criteria are met. The criteria can include the user name, source address and
incoming interface, destination address, schedule, IP protocol (ICMP, UDP, TCP, etc.) and
port.
The actions that can be taken include:
• Routing the packet to a different gateway, outgoing interface, VPN tunnel, or trunk.
• Limiting the amount of bandwidth available and setting a priority for traffic.
