Configuring the IzoT Router DHCP Server

You can configure the IzoT Router to be a DHCP server for LonTalk/IP devices on the LON channels attached to the IzoT Router, or to relay DHCP messages to an external DHCP server located on the LAN. You can use the IzoT Router DHCP server for LonTalk/IP device IP address assignment when you are not using an IzoT Net Server or LNS Server to manage LonTalk address assignment, for example when using the interoperable self-installation (ISI) protocol to create a self-installed network without an IzoT Net Server or LNS Server.
