Policy-based routing (PBR) is a technique used in computer networking to direct network packets based on defined criteria beyond the standard destination-based routing. Unlike traditional routing, which forwards packets solely based on their destination address, PBR allows administrators to customize routing decisions according to various factors such as source address, type of service, protocol, or application.

Introduction


Policy-based routing (PBR) is a technique used in computer networking to direct network packets based on defined criteria beyond the standard destination-based routing. Unlike traditional routing, which forwards packets solely based on their destination address, PBR allows administrators to customize routing decisions according to various factors such as source address, type of service, protocol, or application.

With policy-based routing, network administrators can implement specific rules or policies to dictate the path that packets should take through the network. This flexibility enables organizations to optimize traffic flow, prioritize certain types of traffic, enforce security measures, and manage network resources more efficiently.

Prerequisites & Topology


Before proceeding with the confuration, ensure that all requirements are met:

  1. Before starting you need to have 3 different WAN connections. In this case we are going to use: Wi-fi WAN, Wired WAN and Mobile WAN.

Configuration


If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Configuring VLANs


Open router‘s WebUI and navigate to Network → VLAN → Port Based configuration:

Port based VLAN


Add new VLANs by clicking Add Button.png and Make following changes:

  1. VLAN ID: 1 | lan1: Untagged | Lan2: Off | Lan3: Off | lan4: Untagged | Wan: Off
  2. VLAN ID: 3 | lan1: Off | Lan2: Untagged | Lan3: Off | lan4: Off | Wan: Off
  3. VLAN ID: 5 | lan1: Off | Lan2: Off | Lan3: Untagged | lan4: Off | Wan: Off

General Settings


Make the following changes:

  1. Enter Name : LAN_VLAN_ETH0

Make the following changes:

  1. Enable Interface: on
  2. Enter Name : LAN_VLAN_5
  3. Enter IPV4 address: 192.168.5.1
  4. Enable DHCPv4: on
