LAN Screens
This chapter describes how to configure LAN settings.
5.1 LAN Overview
Local Area Network (LAN) is a shared communication system to which many computers are
attached. The LAN screens can help you configure a LAN DHCP server, manage IP addresses,
and partition your physical network into logical networks.
5.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the HomeSafe
as a DHCP server or disable it. When configured as a server, the HomeSafe provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
5.2.1 IP Pool Setup
The HomeSafe is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the HomeSafe itself) in the
lower range for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that
you may have.
5.2.2 System DNS Servers
Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter.
5.3 LAN TCP/IP
The HomeSafe has built-in DHCP server capability that assigns IP addresses and DNS servers to
systems that support DHCP client capability.
5.3.1 Factory LAN Defaults
The LAN parameters of the HomeSafe are preset in the factory with the following values:
¾ IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
¾ DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need to
be configured.
5.3.2 IP Address and Subnet Mask
Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for this
information.
5.3.3 RIP Setup
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange
routing information with other routers. RIP Direction controls the sending and receiving of RIP
