If the SA is not available in every level, the kernel will request

|
|
|
the SA from the key exchange daemon.

A value of

|
|
|
.Li default
|
2006-09-18 11:55:10 +00:00
|
|
|
tells the kernel to use the system wide default protocol
|
|
|
|
e.g.\& the one from the
|
2000-01-06 12:40:54 +00:00
|
|
|
.Li esp_trans_deflev
|
2000-07-04 16:22:05 +00:00
|
|
|
sysctl variable, when the kernel processes the packet.
|
2006-09-18 11:55:10 +00:00
|
|
|
A value of
|
|
|
|
.Li use
|
2006-01-08 13:59:44 +00:00
|
|
|
means that the kernel will use an SA if it is available,
|
|
|
|
otherwise the kernel will pass the packet as it would normally.
|
2006-09-18 11:55:10 +00:00
|

A value of
|
|
|
|
.Li require
|
2006-01-08 13:59:44 +00:00
|
|
|
means that an SA is required whenever the kernel sends a packet matched
|
|
|
|
that matches the policy.
|
2006-09-18 11:55:10 +00:00
|

|
|

.Li unique
|
2006-01-08 13:59:44 +00:00
|
|
|
level is the same as
|
|
|
|
.Li require
|
|
|
|
but, in addition, it allows the policy to bind with the unique out-bound SA.
|
|
|
|
For example, if you specify the policy level
|
2003-11-05 09:47:54 +00:00
|
|
|
.Li unique ,
|
|
|
|
.Xr racoon 8
|
|
|
|
will configure the SA for the policy.
|
|
|
|
If you configure the SA by manual keying for that policy,
|
2001-06-11 12:39:29 +00:00
|
|
|
you can put the decimal number as the policy identifier after
|
|
|
|
.Li unique

|
separated by colon

.Ql :\&
|
2006-01-08 13:59:44 +00:00

as in the following example:

|
|
|
.Li unique:number .
|
2004-06-05 20:22:15 +00:00
|
|
|
In order to bind this policy to the SA,
|
2001-06-11 12:39:29 +00:00
|
|
|
.Li number
|
2006-09-18 11:55:10 +00:00
|
|
|
must be between 1 and 32767,
|
2006-01-08 13:59:44 +00:00
|
|
|
which corresponds to
|
2003-11-05 09:47:54 +00:00

2006-09-18 11:55:10 +00:00

When you want to use an SA bundle, you can define multiple rules.
|
|
|
|
For
|
2006-01-08 13:59:44 +00:00
|
|
|
example, if an IP header was followed by an AH header followed by an
|
|
|
|
ESP header followed by an upper layer protocol header, the rule would
|
|
|
|
be:
|
2003-11-05 09:47:54 +00:00
|
|
|
.Dl esp/transport//require ah/transport//require ;
|
|
|
|
The rule order is very important.
