LABEL DESCRIPTION
LAN Gateway IP This shows the LAN port’s Gateway IP address.
LAN Subnet Mask This shows the LAN port’s subnet mask.
LAN DHCP Select Enable to activate DHCP for LAN.
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients (computers) to obtain TCP/IP configuration at startup from a server. Enable the
DHCP server unless your ISP instructs you to do otherwise. Select Disable to stop the
NR2101 acting as a DHCP server. When configured as a server, the NR2101 provides TCP/
IP configuration for the clients. If not, DHCP service is disabled and you must have another
DHCP server on your LAN, or else the computers must be manually configured. When set
as a server, fill in the following four fields.
LAN DHCP Start IP This field specifies the first of the contiguous addresses in the IP address pool for LAN.
LAN DHCP End IP This field specifies the last of the contiguous addresses in the IP address pool for LAN.
LAN DHCP Lease Time This is the period of time DHCP-assigned addresses is used. DHCP automatically assigns IP
addresses to clients when they log in. DHCP centralizes IP address management on
central computers that run the DHCP server program. DHCP leases addresses, for a
period of time, which means that past addresses are “recycled” and made available for
future reassignment to other systems.
