Hi,
there was already an issue (https://forum.opnsense.org/index.php?topic=16970.msg77255) reported for 20.1, but this seems still not to be resolved for 20.7: static routes which target into a routed IPsec interface (e.g. ipsec2000) keep disappearing. I can observe this on several OPNsense instances and did not really find a workaround, but manually pressing the "Apply" button in the routing configuration.
How to troubleshoot this? Which service is responsible for applying static routes?
Thanks and BR
Manuel
