# for PacketiX VPN / SoftEther VPN Server
#
# !!! AUTO-GENERATED BY SOFTETHER VPN SERVER MANAGEMENT TOOL !!!
#
# !!! YOU HAVE TO REVIEW IT BEFORE USE AND MODIFY IT AS NECESSARY !!!
#
# This configuration file is auto-generated. You might use this config file
# in order to connect to the PacketiX VPN / SoftEther VPN Server.
# However, before you try it, you should review the descriptions of the file
# to determine the necessity to modify to suitable for your real environment.
# If necessary, you have to modify a little adequately on the file.
# For example, the IP address or the hostname as a destination VPN Server
# should be confirmed.
#
# Note that to use OpenVPN 2.0, you have to put the certification file of
# the destination VPN Server on the OpenVPN Client computer when you use this
# config file. Please refer the below descriptions carefully.


###############################################################################
# Specify the type of the layer of the VPN connection.
#
# To connect to the VPN Server as a "Remote-Access VPN Client PC",
# specify 'dev tun'. (Layer-3 IP Routing Mode)
#
# To connect to the VPN Server as a bridging equipment of "Site-to-Site VPN",
# specify 'dev tap'. (Layer-2 Ethernet Bridgine Mode)
dev tun


###############################################################################
# Specify the underlying protocol beyond the Internet.
# Note that this setting must be correspond with the listening setting on
# the VPN Server.
#
# Specify either 'proto tcp' or 'proto udp'.

proto tcp

# The destination hostname / IP address, and port number of
# the target VPN Server.
#
# You have to specify as 'remote <HOSTNAME> <PORT>'. You can also
# specify the IP address instead of the hostname.
#
# Note that the auto-generated below hostname are a "auto-detected
# IP address" of the VPN Server. You have to confirm the correctness
# beforehand.
#
# When you want to connect to the VPN Server by using TCP protocol,
# the port number of the destination TCP port should be same as one of
# the available TCP listeners on the VPN Server.
#
# When you use UDP protocol, the port number must same as the configuration
# setting of "OpenVPN Server Compatible Function" on the VPN Server.

remote 219.100.37.211 443


###############################################################################
# The HTTP/HTTPS proxy setting.
#
# Only if you have to use the Internet via a proxy, uncomment the below
# two lines and specify the proxy address and the port number.
# In the case of using proxy-authentication, refer the OpenVPN manual.

;http-proxy-retry
;http-proxy [proxy server] [proxy port]

#
# Default setting is good. Modify it as you prefer.
# When you specify an unsupported algorithm, the error will occur.
#
# The supported algorithms are as follows:
# cipher: [NULL-CIPHER] NULL AES-128-CBC AES-192-CBC AES-256-CBC BF-CBC
# CAST-CBC CAST5-CBC DES-CBC DES-EDE-CBC DES-EDE3-CBC DESX-CBC
