The addressing technology from
which URLs are created. Technically,
URLs such as HTTP:// and FTP:// are
specific subsets of URLs, although the
term URL is mostly heard.
An IP address that the remote user
should connect to access Portal/VPN
(in clientless mode) or simply the VPN
(in transparent mode).
A virtual SSL server handles a specific
service on the VPN Gateway, such as
HTTPS, SMTPS, IMAPS, or POP3S.
You can create up to 256 virtual
SSL servers per NVG cluster. To
authenticate itself towards clients
making requests for the specified
service, the virtual SSL server is
configured to use a digital certificate.
VLANs are commonly used to split
up groups of network users into
manageable broadcast domains,
to create logical segmentation of
workgroups, and to enforce security
policies among logical segments.
A widely-used specification for
digital certificates that has been a
recommendation of the ITU since
1988.
The X Window System (commonly
X11 or X) is a windowing system for
bitmap displays. It is the standard
toolkit and protocol to build graphical
user interfaces on Unix, Unix-like
operating systems and OpenVMS,
and is available for almost all modern
operating systems. The VPN Gateway
supports secure display of X11 across
the Internet by way of X11 Forwarding,
supported by the SSH applet on
the Portal's Advanced tab and the
Terminal link type.
