3.1.7.2 Connection Supervisor
The connection supervisor monitors connectivity and automatically recovers the connections in case of link
loss.
First you should check the option “monitor the connection establishment” to make sure that problems during
connections establishment are detected and recovered.
Second the active connection should be monitored. If you are running an IPsec or OpenVPN based VPN we
recommend to use the protocol integrated monitoring service (IPsec DPD or OpenVPN keep-alive). Else you
should configure and enable the ping monitor application.

Host 2: Reference host 2 to which IP connectivity is checked by sending probes (optional)
The test is considered successful if host 1 or 2 answers.
Source IP address: Source IP address to be used as source of the ping probes
