•Gateway. IP address of the Default Gateway or Router that the node will use.
•Netmask. Subnet Mask for the LAN that the node will be on.
•DNS. Domain Name Server. The DNS that the node will use. DNS is a server with a
database. The database translates a domain name into a corresponding IP address. For
example, “USR.com” resolves into IP address 231.222.320.4. Communications over the
LAN between the node and USR.com web site use this address.
•Lease Time. Number of days that the node can use a DHCP lease. Subsequently, you
must renew the lease with the DHCP server.
DHCP Relay
Suppose that a Dynamic Host Configuration Protocol (DHCP) server resides on a different
LAN than the node broadcasting for DHCP service. Then the DHCP broadcast request must
be forwarded across the router/WAN to a subnet where a DHCP server resides. The router
must relay the DHCP request. DHCP relay assures that the requesting node receives an IP
address that corresponds to the node’s subnet. The router must have a record of the DHCP
server’s IP address. With this address, the router can correctly direct the request to the
appropriate DHCP server.
After you input the IP address into the menu, start the relay agent by clicking Start.
