Basic Setup & Internet Access

3.4 DSL/Cable Modem Internet Access

Before you connect a broadband access device, e.g. a DSL/Cable

modem, to the router, you need to know what kind of Internet access

is provided by your ISP.

The following sections deal with four widely-used broadband access

services. These are PPPoE Client, PPTP Client and Static IP for

DSL, and Dynamic IP (DHCP Client) for Cable. In most cases, you

will get a DSL or Cable modem from the broadband access service

provider. The router is connected behind the broadband device (i.e.

DSL/Cable modem) and works as a NAT or IP router for broadband

and ISDN connections.

In addition to broadband access capabilities, the ISDN port can do

dial backup, or provide remote access and remote management func-

tions to support more flexible network connectivity. The following ap-

plication scenarios show that the head office is capable of getting on

to the Internet through the Vigor2200 and a broadband device, and

simultaneously connecting to the branch office via an ISDN network.

Note:

On the Vigor2200E the ISDN dial backup function, re-

mote access, and LAN-to-LAN connectivity are not sup-

ported.
