IPSec function
The principle features of IPSec are the encryption and authentication of all
traffic at the IP layer. A further functional area is the key management.
Authentication assures that a received packet was really sent by the source
indicated in the packet header, and that the data in the packet coincide with
the data sent. By using encryption, listening of the data by third parties has no
effect. The key management is responsible for the secure exchange of the
keys. This feature needs to be enabled on the operating system on client's side
as well. Otherwise, the incoming data is not processed as pinging is not a
function.
