DHCP Table

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 NBG’s LAN as a DHCP

server or disable it. When configured as a server, the NBG provides the TCP/IP configuration for the

clients. If DHCP service is disabled, you must have another DHCP server on that network, or else

the computer must be manually configured.

Click the

DHCP Table (Details...)

hyperlink in the

Status

screen. Read-only information here

relates to your DHCP status. The DHCP table shows current DHCP client information (including

IP

Address

,

Host

Name

and

MAC Address

) of all network clients using the NBG’s DHCP server.
