Introduction

A DHCP relay agent allows the DHCP clients to obtain IP addresses from a DHCP server that is not configured on the same LAN.

This article provides a configuration example with details on how to set-up a DHCP relay over a L2TPv3 VPN.

Prerequisites

You will need:

  • Two RUT or RUTX devices (one as Server and other as Client)
  • A PC acting as a Host for testing
  • Both routers must have a Public Static or Public Dynamic IP addresses

Configuration Scheme

I will paste a Topology Image here

DHCP Server Settings

DHCP Pool

Enter the router's WebUI, go to Network > Interfaces > Ethernet LAN and click the 'Edit' button on the right side of the interface to set the LAN network address.

LAN network for DHCP server

Under DHCP SERVER set parameters for the DHCP pool.
