Dynamic Addressing, using DHCP-Relay

Let us consider that you have several IP networks 'behind' other routers, but you want to keep all DHCP servers on a single router. To do this, you need a DHCP relay on your network which relies DHCP requests from clients to DHCP server.

This example will show you how to configure a DHCP server and a DHCP relay which serve 2 IP networks - 192.168.1.0/24 and 192.168.2.0/24 that are behind a router DHCP-Relay.

[DHCP-Server]

Local 192.168.0.1/24

[DHCP-Relay]

Local1

192.168.1.1/24

Public

10.1.0.2/24 Internet

Public 192.168.0.2/24

Local2

192.168.2.1/24
