in USG FLEX H Series

According to the release notes, Connectivity Check for IPSec VPN was implemented in this new firmware.

How can I configure this? I am not seeing it under the IPSec VPN settings.

    Hi @p4_greg and @PeterUK,

    Regarding the Connectivity Check feature for USG FLEX H Series devices, please note that it is not intended for configuration purposes. However, you can locate the “Connectivity Check” menu under VPN Status > IPSec VPN > Site to Site VPN to check the connection to a remote client through the VPN tunnel.

    That explains why I could not find it….I assumed the release notes were referring to the Connectivity Check which was previously available in the VPN Connection settings on the non-H/ZLD-based firewalls.

    It has been helpful in the past when the connection gets 'stuck' and traffic does not flow over the VPN, which sometimes happens after one side of the VPN connection experiences internet issues. The connectivity check feature available on previous would automatically detect this and reset the VPN connection, which usually restored connectivity.

    Are there any plans to add this feature back?
