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 (Net 2)
- through a layer-2 switch port (Net 3)
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.
