.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.
