OTE

The Firebox model 700 does not support VPN Manager.

High Availability

WatchGuard High Availability software lets you install a
second, standby Firebox on your network. If your primary
Firebox fails, the second Firebox automatically takes over
to give your customers, business partners, and employees
virtually uninterrupted access to your protected network.

High Availability is bundled with the WFS software, but it
is available for use only if you enable the High Availability
checkbox when installing WFS and enter your license key.

Mobile User VPN

Mobile User VPN is the WatchGuard IPSec implementa-
tion of remote user virtual private networking. Mobile
User VPN connects an employee on the road or working
from home to trusted and optional networks behind a Fire-
box using a standard Internet connection, without compro-
mising security. WatchGuard Mobile User VPN software
easily integrates into your Firebox System, allowing your
mobile users to securely connect to your network. VPN
traffic is encrypted using DES or 3DES-CBC, and authenti-
cated through MD5 or SHA-1.

SpamScreen

SpamScreen helps to control “spam”–email sent to you or
your end users without permission. Spam consumes valu-
able bandwidth on your Internet connection and on the
hard disk space and CPU time of your mail server. If
