About IP networking
The 3100 ICP system provides small and medium-sized
businesses with a Local Area Network (LAN) and Internet
connectivity. This chapter provides step-by-step
procedures for
• connecting the system directly to the Internet through
a cable or DSL modem using
– static IP addressing
– a DHCP client (typically used with a cable
modem)
– PPPoE (typically used with a DSL modem)
• connecting the system to an existing LAN through
– the WAN Ethernet port
– through a layer-2 switch port
• using a remote DHCP server
• changing the assigned DHCP IP address range
• configuring Domain Naming Service (DNS)
• assigning a gateway
• programming dial-up access to an ISP
• restricting external access with a firewall.
Only qualified Network Engineers should install the 3100
ICP system into an existing LAN.
Refer to the IP Routing section of the Technical Manual
for detailed IP networking information. From the system
tool, click Help, click IP Networking.
