Although dial-up networking using
modems and ISDN lines is certainly still an option, it has become less and less popular
due to the proliferation and general availability of high-speed Internet connections
from practically anywhere. VPN connections are more cost-effective and offer a betterperforming
user experience than DUN could ever dream of, even when taking advantage
of multilink to pool multiple DUN connections together to achieve a higher data
transfer rate. SSTP is one of the most exciting new features in RRAS that can significantly
reduce the cost for implementing and supporting VPN access.

RRAS in Windows Server 2008 isn??™t that different from what was available in Windows
Server 2003, other than the support for IPv6 and SSTP. Although RRAS does
provide the ability for the server to provide routing services, you should only do so
in situations where implementing a true dedicated hardware router is either impractical,
cost-prohibitive, or both. While using RRAS makes it easy to provide remote access
functionality to your users, you should carefully review and test each and every RRAS
option to ensure that you don??™t sacrifice the security of your network for the functionality
that RRAS provides. RRAS servers are typically deployed outside the trusted network
boundary and are exposed to the Internet.
