7.1 Installation Precautions
This section describes the precautions to take before installing
PacketiX VPN Server 2.0.
7.1.1 Checking the Operating Environment
Before installing PacketiX VPN Server to a computer, check that the
computer hardware and operating system support PacketiX VPN Server.
PacketiX VPN Server supports Windows, Linux, FreeBSD, Solaris, and
Mac OS X; however, this product formally supports only operating systems
with Windows 2000 or later and certain Linux distributions. PacketiX VPN
Server can be installed on other operating systems, but SoftEther
Corporation is not responsible for its operations. For information about
the operating environment of PacketiX VPN Server, please refer to
「12.1 PacketiX VPN Server 2.0 Specs」.
Before installing PacketiX VPN Server, be sure to back up data stored
in the installation directory of the computer (including the system
registry in Windows).
7.1.2 Hard Disk Space
As described in 「3.10 Logging Service」, PacketiX VPN Server writes large operation
log files to the hard disk during operation. In addition, when the hard
disk space reaches a certain size, VPN Server deletes the oldest log
files written to the hard disk during VPN Server operation.
Although the data size of logs written by VPN Server varies greatly
depending on the operation status of VPN Server, the number of users
connected on a daily basis, and the selection of saved packet log items
configured by the Virtual HUB administrator, as a guideline, it is a
good idea to have between 30 and 100 GB of available disk space when
using VPN Server for a general remote-access VPN or for a VPN connection
between bases.
7.1.3 CPU Processing Speed
The processing speed of VPN Server depends on the CPU speed.
Therefore, check that the CPU speed of the hardware you want to use as
the VPN server computer has sufficient speed. If the CPU speed is too
slow, we recommend upgrading the system.
As a guideline for the CPU speed, we recommend providing a CPU with a
speed of 2.0 GHz or faster when connecting to a network using a physical
line with a communication speed of 100 Mbps. If the CPU speed is too
slow, the communication delay time may increase and throughput may
decrease.
7.1.4 Conflicting Software
It is essential that you make sure that the operation speed of VPN
Server is not adversely affected and server operations are not disrupted
by software conflicts that can occur when VPN Server is installed on a
computer with a personal firewall or antivirus software from a different
manufacturer. If there are signs that the VPN functions are not
operating properly due to a conflict with this type of software, we
recommend temporarily disabling that software and try operating VPN
Server again.
Please note that VPN Server conflicts with VPN Bridge. Generally, VPN
Bridge does not need to be installed on the same computer on which VPN
Server is installed.
