DHCP
10.1 DHCP
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the
NBG420N’s LAN as a DHCP server or disable it. When configured as a server, the NBG420N
provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have
another DHCP server on your LAN, or else the computer must be manually configured.
