CHAPTER 19
Preparing a Host for Remote
User VPN
Remote user virtual private networking (RUVPN) establishes a secure connection
between an unsecured remote host and a protected network over an unsecured
network. RUVPN connects an employee on the road or working from home to trusted
and optional networks behind a Firebox using a standard Internet dial-up connection
without compromising security.
The WatchGuard Firebox System offers two types of RUVPN:
• Remote User PPTP – Uses the Point-to-Point Tunneling Protocol. This type of
RUVPN is included with the basic WatchGuard package and supports up to 50
concurrent sessions per Firebox. It works with any Firebox encryption level.
• Mobile User VPN – Uses Internet Protocol Security (IPSec). This type of
RUVPN is an optional feature of the WatchGuard package. It also requires that
the Firebox be approved and upgraded to strong or medium encryption level.
RUVPN requires configuration of both the Firebox and the end-user remote host
computers. This section describes how to configure a remote host for Remote User
VPN with PPTP. For information on configuring the Firebox, see “Configuring the
Firebox for Remote User VPN” on page 133.
For information on configuring a remote host for Mobile User VPN, see the Mobile
User VPN brochure provided with Mobile User VPN licenses. You can download a
copy from the LiveSecurity Service Web site.
