DESCRIPTION
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132)
allows individual clients (computers) to obtain TCP/IP configuration at
startup from a server.
Select None if you do not want to configure DNS servers. If you do not
configure a DNS server, you must know the IP address of a machine in
order to access it.
When configured as a Server, the device provides TCP/IP configuration
for the clients. When set as a Server, fill in the rest of the DHCP setup
fields.
Select Relay to have the device act as a DNS proxy. The device tells
the DHCP clients on the LAN that the device itself is the DNS server.
When a computer on the LAN sends a DNS query to the device, the
device forwards the query to the device's system DNS server and
relays the response back to the computer. You can select Relay and
enter an IP Pool Starting Address. The First DNS Server IP and
Second DNS Server IP will appear as read only fields.
This field specifies the first of the contiguous addresses in the IP
address pool.
If Relay is selected in the DHCP field above, then type the IP address
of the actual, remote DHCP server here.
This field specifies the size, or count of the IP address pool.
The device passes a DNS (Domain Name System) server IP address (in
the order you specify here) to the DHCP clients. Type your First DNS
Server IP and
Second DNS Server IP addresses in these fields.
Type the IP address of the device in dotted decimal notation.
The subnet mask specifies the network number portion of an IP
address. Unless you are implementing subnetting, use the "natural"
subnet mask, which is usually 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.
