VPN

For a Central DHCP Relay Agent, selecting this checkbox allows the device to act

as a VPN Relay agent and supports DHCP requests arriving over VPN tunnels

using IKE. The device will forward the requests onto the DHCP server.

Remote DHCP

Relay Agent

Select this option if the device is connected to a client network that sends DHCP

lease requests. In this configuration, the device listens for DHCP requests from its

LAN. This option is recommended for an device in a remote office that is relaying

DHCP requests to a central DHCP server in the head office.

VPN Tunnel If Remote DHCP Relay Agent is selected, this parameter identifies the VPN Tunnel

the X family device uses to pass DHCP requests to the central DHCP relay agent.

Note If you are using DHCP Relay over VPN, any LAN devices attached to the

Remote VPN Relay agent that are not using DHCP must be configured as Static

Reservations. (See “

Static Reservations” on page 174). To configure, navigate to

Network > DHCP Server. Then, select the Static Reservations page.

You can only use DHCP Relay Over VPN when the VPN between two devices is

configured to use Internet Key Exchange (IKE).

Note Make sure that the tunnels connecting to device configured as

the Remote VPN Relay agent are configured as Destination network

addresses assigned by DHCP in the Tunnel Setup section of the

VPN - Create Security IPSec Configuration page.
