DHCP Server Menu
The SPEEDLAN 9200 Configurator allows you to define a DHCP server on the Ethernet
interface. A DHCP server is configured with a table of Ethernet addresses, ranges of IP
addresses and maps that are assigned to client network devices asking for the network
settings. The DHCP server uses a "lease" to determine the length of time that a device
