DESCRIPTION
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132)
allows individual clients (workstations) to obtain TCP/IP configuration
at startup from a server. Unless you are instructed by your ISP, leave
this field set to Server. When configured as a server, the device
provides TCP/IP configuration for the clients. When set as a server, fill
in the IP Pool Starting Address and Pool Size fields.
Select Relay to have the device forward DHCP requests to another
DHCP server. When set to Relay, fill in the DHCP Server IP field.
Select None to stop the device from acting as a DHCP server. When
you select None, you must have another DHCP server on your LAN, or
else the computers must be manually configured.
This field specifies the first of the contiguous addresses in the IP
address pool.
Type the IP address of the DHCP server to which you want the device
to relay DHCP requests. Use dotted decimal notation. Alternatively,
click the right mouse button to copy and/or paste the IP address.
Type the IP address of the WINS (Windows Internet Naming Service)
server that you want to send to the DHCP clients. The WINS server
keeps a mapping table of the computer names on your network and
the IP addresses that they are currently using.
This field specifies the size, or count of the IP address pool.
These fields are enabled if the DHCP Mode is Server. Specify the DNS
servers that are provided to DHCP clients.
Select From ISP if you want the device to use corresponding DNS
server provided by the ISP.
Select User-Defined and specify the IP address if you want the device
to use the specific DNS server.
Select DNS Relay if you want the device to
Type the IP address of the device in dotted decimal notation.
192.168.1.1 is the factory default.
The subnet mask specifies the network number portion of an IP
address. The device automatically calculates the subnet mask based
on the IP address that you assign. Unless you are implementing
subnetting, use the subnet mask computed by the device, which is
255.255.255.0.
RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a
router to exchange routing information with other routers. The RIP
Direction field controls the sending and receiving of RIP packets.
Select the RIP direction from Both/In Only/Out Only/None. When
set to Both or Out Only, the device broadcasts its routing table
periodically. When set to Both or In Only, it incorporates the RIP
information that it receives; when set to None, it does not send any
RIP packets and ignores any RIP packets received. Both is the default.
