.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.
