Enable IPsec
|
||||||
|
============
|
||||||
|
Default IPsec transformation with ESP encapsulation plus Transport mode
|
||||||
|
could be enabled by simply setting:
|
||||||
|
|
||||||
|
pgset "flag IPSEC"
|
||||||
|
pgset "flows 1"
|
||||||
|
|
||||||
|
To avoid breaking existing testbed scripts for using AH type and tunnel mode,
|
||||||
|
user could use "pgset spi SPI_VALUE" to specify which formal of transformation
|
||||||
|
to employ.
