# This script supports running multiple instances of mlvpn
|
|
# To run additional instances link this script to something like
|
|
# % ln -s mlvpn mlvpn_foo
|
|
# and define additional mlvpn_foo_* variables in one of
|
|
# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/mlvpn_foo
|
|
#
|
|
# Below NAME should be substituted with the name of this script. By default
|
|
# it is mlvpn, so read as mlvpn_enable. If you linked the script to
|
|
# mlvpn_foo, then read as mlvpn_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 mlvpn
|

# NAME_if= # driver(s) to load, set to "tun", "tap" or "tun tap"

# # it is OK to specify the if_ prefix.

# # optional:
|

# NAME_flags= # additional command line arguments

# NAME_configfile="/usr/local/etc/mlvpn/NAME.conf" # --config file
