[strongSwan-dev] MIB for IKE

Hi Krishna,

strongSwan offers a High Availability Solution based on a Cluster of
two physical hosts:


With this solution the VPN clients are not aware of the redundant
hardware. They just connect to a virtual VPN gateway having a constant
Layer3 IP and Layer2 MAC address. Therefore we don't need RFC 6311
for synchronisation. The update of ESP sequence numbers is continuously
done via Linux Cluster IP where both gateways get all ESP packets
but only half of them are actually processed by each host.

The mirroring of IKE and ESP keys is donevia a proprietary socket
protocol over a either a dedicated or ESP-encrypted public network
link between the two gateways. Therefore we provide hooks where
ESP keying data can be extracted, although not in the form of
an official SNMP MIB.

For more information on HA please contact Martin Willi.

Best regards
