Chapter 5 Device Network Settings The following table describes the fields in this screen. Table 14 Device Operation > Device Configuration > Network > LAN > LAN (Prestige) LABEL DESCRIPTION DHCP Mode 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. IP Pool Starting This field specifies the first of the contiguous addresses in the IP Address address pool. DHCP Server IP If Relay is selected in the DHCP field above, then type the IP address of the actual, remote DHCP server here. Pool Size This field specifies the size, or count of the IP address pool. First DNS Server IP Second DNS Server IP 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. TCP/IP IP Address Type the IP address of the device in dotted decimal notation. IP Subnet Mask 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 Direction 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.
