Targets of the Manual
The PacketiX VPN 2.0 official manual contains an overview of and
information on how to use the latest release of next-generation VPN
communications software provided by SoftEther Corporation, how to
construct a VPN, and how to solve problems. The manual is designed for
network administrators, system administrators, system instructors, IT
professionals and end users with detailed knowledge of computers who
require information about the specifications of PacketiX VPN 2.0
If you want to get a detailed understanding of PacketiX VPN 2.0 and
peripheral technologies, you should carefully read the entire manual. If
not, you may also read just the required sections and skip the
One of the most important features of PacketiX VPN 2.0 is that, when
utilizing the advanced and efficient VPN functions, the end user is able
to use VPN communications without a detailed knowledge of VPN. In other
words, the software is easy to use and sufficient security is maintained
even when in the initial state.
In order to use the various functions of PacketiX VPN 2.0 properly,
we recommend you read the entire manual. If using VPN of ordinary scale,
all you need is some knowledge of TCP/IP and VPN. In this case, you may
not have to read the entire manual.
