IPSec module

The IPSec module shows information about IPSec ESP traffic and sequence counter correctness. Values about packets, bytes, packets per second and bytes per second of IPSec ESP traffic are shown together with a graph over time. A PCAP button allows for capturing that traffic. A sequence counter analysis is performed. Several counter provide information about:

• Sequence number repeated: For two subsequent IPSec ESP packets the sequence number was exactly the same.
• Sequence number too high: Between two subsequent packets the sequence number did not increase by 1 but with a higher value. This is an indication about a packet loss.
• Sequence number too low: Between two subsequent packets the sequence number did not increase by 1.

The latter packet had a lower value.
