strongSwan

= ipsec.conf =

strongSwan's ''/etc/ipsec.conf'' configuration file consists of three different section types:

* [wiki:ConfigSetupSection config setup] defines general configuration parameters
* [wiki:ConnSection conn <name>] defines a connection
* [wiki:CaSection ca <name>] defines a certification authority

There can be only one [wiki:ConfigSetupSection config setup] section but
an unlimited number of [wiki:ConnSection conn] and [wiki:CaSection ca] sections.

All parameters belonging to a section must be indented by at least one space or tab
character. The rest of the line after a '#' character is treated as a comment.
Comments within a section must also be indented.
