Gateway Alarm is causing ipsec tunnels and other stuff to be reset/reloaded? Why?
- Two WAN Gateways inside a Gateway Group
- "UMGW" configured as Tier2, it's not active since the other Tier1 gateway is active
- Gateway monitoring configured with IPs 22.214.171.124 for UMGW and 126.96.36.199 for the other one
- The IPSEC tunnel is configured to use the other gateay ("Interface" in general configuration of the ipsec tunnel is set to the other interface, not the one belonging to "UMGW")
In the logs I see the "UMGW" going down and then the ipsec tunnels as well as other stuff being restarted:

Why would pfSense restart the ipsec tunnel when an interface the ipsec tunnel is not using goes down? Is this intended behaviour? Can this be configured somehow?
Does this also cause other outages or reset of connections? I see "reloading filter" there, what does this mean exactly, are the state tables cleared maybe?
