+ .I _updown
+ is invoked by pluto when it has brought up a new connection. This script
+ is used to insert the appropriate routing entries for IPsec operation.
+-It can also be used to insert and delete dynamic iptables firewall rules.
+-The interface to the script is documented in the pluto man page.
++It also inserts and deletes dynamic iptables firewall rules. IMPORTANT!
++By default, it will ACCEPT as appropriate on the INPUT, OUTPUT, FORWARD
++tables. Most distributions will want to change that to provide more
++flexibility in their firewall configuration.
++The script looks for the environment variables
++.B IPSEC_UPDOWN_RULE_IN
++for the iptables table it should insert into,
++.B IPSEC_UPDOWN_DEST_IN
++for where the rule should -j jump to,
++.B IPSEC_UPDOWN_RULE_OUT
++.B IPSEC_UPDOWN_DEST_OUT
++for the same on outgoing packets, and
++.B IPSEC_UPDOWN_FWD_RULE_IN
++.B IPSEC_UPDOWN_FWD_DEST_IN
++.B IPSEC_UPDOWN_FWD_RULE_OUT
++.B IPSEC_UPDOWN_FWD_DEST_OUT
++respectively for packets being forwarded to/from the local networks.
