|
# This script supports running multiple instances of openvpn.
|
|
# To run additional instance link this script to something like
|
|
# % ln -s openvpn openvpn_foo
|
|
# and define additional openvpn_foo_* variables in one of
|
|
# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/openvpn_foo
|
|
#
|
|
# Below NAME should be substituted with the name of this script. By default
|
|
# it is openvpn, so read as openvpn_enable. If you linked the script to
|
|
# openvpn_foo, then read as openvpn_foo_enable etc.
|
|
#
|
|
# The following variables are supported (defaults are shown).
|
|
# You can place them in any of
|
|
# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/NAME
|
|
#
|
|
# NAME_enable="NO" # set to YES to enable openvpn
|
|
# NAME_if="" # driver(s) to load, set to "tun", "tap" or "tun tap"
|
|
#
|
|
# # optional:
|
|
# NAME_flags="" # additional command line arguments
|
|
# NAME_configfile="%%PREFIX%%/etc/openvpn/NAME.conf" # --config file
|
|
# NAME_dir="%%PREFIX%%/etc/openvpn" # --cd directory
|
|
#
|
|
# You also need to set NAME_configfile and NAME_dir, if the configuration
|
|
# file and directory where keys and certificates reside differ from the above
|
|
# settings.
|
|
#
|
|
# Note that we deliberately refrain from unloading drivers.
