Gateway Group slow (or never) to switch back to Tier 1
See https://forum.netgate.com/topic/136852/2-4-4-gateway-group-slow-or-never-to-switch-back-to-tier-1. (No responses yet as of this posting.)
I have a gateway group with 2 gateways, one at Tier 1 and the other at Tier 2. I've been having lots of trouble with my Tier 1 link lately and pfSense will switch over to the Tier 2 link, but when the Tier 1 gateway comes back within limits (latency, packet loss) the routing does not switch back to the Tier 1 gateway. The Gateways widget on the home page shows the Tier 1 as "online" as does Status -> Gateways and Status -> Gateway Groups. The log file shows an alarm for latency and then cleared for latency.
I've set that gateway group as the default gateway and am also sending traffic to it with a LAN firewall rule.

To make things even more complicated, in the workaround mentioned above, the routing actually changes back to the Tier 1 gateway when I mark it as down, so that when the status is "forced offline" it is still routing through that gateway. When I undo the "mark as down" it continues to route through that gateway.

The Gateway Group was set as Trigger Level: Packet Loss or High Latency. I changed that to "Member Down" and now the routing seems to be switching back to the Tier 1 gateway as it should. I'm going to revert to "Packet Loss or High Latency" as a test to see if that triggers the problem.
