Figure 32: IPSec icon
IPSec (Internet Protocol Security) is a set of network protocols and services that
provide security to IP networks by authenticating and encrypting each IP packet of a
data stream. IPSec-protected packets travel through a virtual tunnel or path between
two points. An IPSec tunnel is
up when it has been established between two peers
and is capable of carrying traffic. If it cannot carry traffic it is down .
When IPSec is enabled (IPSec icon present), the modem attempts to establish all
configured tunnels. The status of all configured tunnels at any given time (if IPSec is
enabled) is one of the following:
•
All tunnels are established (green System Status button).
•
Some tunnels are established (orange System Status button).
•
No tunnels are established (red System Status button).
