# strongSwan use yours instead of this default one.
# things that this script gets (from ipsec_pluto(8) man page)
#
# PLUTO_VERSION
# indicates what version of this interface is being
# used. This document describes version 1.1. This
# is upwardly compatible with version 1.0.
#
# PLUTO_VERB
# specifies the name of the operation to be performed
# (prepare-host, prepare-client, up-host, up-client,
# down-host, or down-client). If the address family
# for security gateway to security gateway communica-
# tions is IPv6, then a suffix of -v6 is added to the
# verb.
#
# PLUTO_CONNECTION
# is the name of the connection for which we are
# routing.
#
# PLUTO_NEXT_HOP
# is the next hop to which packets bound for the peer
# must be sent.
#
# PLUTO_INTERFACE
# is the name of the ipsec interface to be used.
#
# PLUTO_REQID
# is the requid of the ESP policy
#
# PLUTO_ME
# is the IP address of our host.
#
# PLUTO_MY_ID
# is the ID of our host.
#
# PLUTO_MY_CLIENT
# is the IP address / count of our client subnet. If
# the client is just the host, this will be the
# host's own IP address / max (where max is 32 for
# IPv4 and 128 for IPv6).
#
# PLUTO_MY_CLIENT_NET
# is the IP address of our client net. If the client
# is just the host, this will be the host's own IP
# address.
#
# PLUTO_MY_CLIENT_MASK
# is the mask for our client net. If the client is
# just the host, this will be 255.255.255.255.
#
# PLUTO_MY_SOURCEIP
# if non-empty, then the source address for the route will be
# set to this IP address.
#
# PLUTO_MY_PROTOCOL
# is the IP protocol that will be transported.
#
# PLUTO_MY_PORT
# is the UDP/TCP port to which the IPsec SA is
# restricted on our side.
#
# PLUTO_PEER
# is the IP address of our peer.
#
# PLUTO_PEER_ID
# is the ID of our peer.
#
# PLUTO_PEER_CA
# is the CA which issued the cert of our peer.
#
# PLUTO_PEER_CLIENT
# is the IP address / count of the peer's client sub-
# net. If the client is just the peer, this will be
# the peer's own IP address / max (where max is 32
# for IPv4 and 128 for IPv6).
#
# PLUTO_PEER_CLIENT_NET
# is the IP address of the peer's client net. If the
# client is just the peer, this will be the peer's
# own IP address.
#
# PLUTO_PEER_CLIENT_MASK
# is the mask for the peer's client net. If the
# client is just the peer, this will be
# 255.255.255.255.
#
# PLUTO_PEER_PROTOCOL
# is the IP protocol that will be transported.
#
# PLUTO_PEER_PORT
# is the UDP/TCP port to which the IPsec SA is
# restricted on the peer side.
#
# PLUTO_XAUTH_ID
# is an optional user ID employed by the XAUTH protocol
#
# PLUTO_MARK_IN
# is an optional XFRM mark set on the inbound IPsec SA
#
# PLUTO_MARK_OUT
# is an optional XFRM mark set on the outbound IPsec SA
#
# PLUTO_UDP_ENC
# contains the remote UDP port in the case of ESP_IN_UDP
# encapsulation
#
# define a minimum PATH environment in case it is not set
