In this blog, we discuss two increasingly important technologies
in remote access: cable modems and virtual private networks
(VPNs). Although Cisco has finally added these topics to the
Remote Access exam, they have not attained the prominence that one might expect compared
to legacy technologies such as ISDN. Cable modems, like DSL, provide high data rates at low
cost, and don’t suffer from the call setup and bonding issues that ISDN includes. In addition to
providing an overview of cable modem and VPN technologies, this chapter also covers the configuration
of IPSec, one of the most common VPN technologies.
