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 from 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 three 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 the DHCP-assigned IP addresses is used. DHCP automatically
assigns IP addresses to client devices 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.
