NAME
openvpn secure IP tunnel daemon.

SYNOPSIS
openvpn [ options ... ]

INTRODUCTION
OpenVPN is an open source VPN daemon by James Yonan. Because OpenVPN tries to be a universal VPN tool offering a great deal of flexibility, there are a lot
of options on this manual page. If you're new to OpenVPN, you might want to skip ahead to the examples section where you will see how to construct simple
VPNs on the command line without even needing a configuration file.

Also note that there's more documentation and examples on the OpenVPN web site: http://openvpn.net/

And if you would like to see a shorter version of this manual, see the openvpn usage message which can be obtained by running openvpn without any parameters.

DESCRIPTION
OpenVPN is a robust and highly flexible VPN daemon. OpenVPN supports SSL/TLS security, ethernet bridging, TCP or UDP tunnel transport through proxies or
NAT, support for dynamic IP addresses and DHCP, scalability to hundreds or thousands of users, and portability to most major OS platforms.

OpenVPN is tightly bound to the OpenSSL library, and derives much of its crypto capabilities from it.

OpenVPN supports conventional encryption using a pre shared secret key (Static Key mode) or public key security (SSL/TLS mode) using client & server certifi Äê
cates. OpenVPN also supports non encrypted TCP/UDP tunnels.

OpenVPN is designed to work with the TUN/TAP virtual networking interface that exists on most platforms.

Overall, OpenVPN aims to offer many of the key features of IPSec but with a relatively lightweight footprint.

OPTIONS
OpenVPN allows any option to be placed either on the command line or in a configuration file. Though all command line options are preceded by a double lead Äê
ing dash (" "), this prefix can be removed when an option is placed in a configuration file.

help Show options.

config file
Load additional config options from file where each line corresponds to one command line option, but with the leading ' ' removed.

If config file is the only option to the openvpn command, the config can be removed, and the command can be given as openvpn file

Note that configuration files can be nested to a reasonable depth.

Double quotation or single quotation characters ("", '') can be used to enclose single parameters containing whitespace, and "
