LABEL DESCRIPTION
IP Address Enter the LAN IPv4 IP address you want to assign to the NR2301 in dotted decimal notation,
for example, 192.168.1.1 (factory default).
Subnet Mask Type the subnet mask of your network in dotted decimal notation, for example
255.255.255.0 (factory default). The NR2301 automatically computes the subnet mask
based on the IP address you enter, so do not change this field unless you are instructed to
do so.
DHCP Server Select Disable to stop the DHCP server on the NR2301.
Select Enable to have the NR2301 act as a DHCP server or DHCP relay agent.
When configured as a server, the NR2301 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, enter the following fields.
Start IP This field specifies the first of the contiguous addresses in the IP address pool.
End IP This field specifies the last of the contiguous addresses in the IP address pool.
Lease Time(s) 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.
MTU Enter the MTU (Maximum Transfer Unit) size for traffic through this connection.
This following part allows you to assign IP addresses on the LAN to specific individual computers based on their MAC
addresses. You can configure up to 10 entries.
ID This is the index number of the entry.
MAC Type the MAC address (with colons) of a computer on your LAN.
IP Type the LAN IP address of a computer on your LAN.
X Click the X next to an entry to clear it.
