Pfsense 2.4.4-RELEASE (amd64) built on Thu Sep 20 09:03:12 EDT 2018 FreeBSD 11.2-RELEASE-p3
WAN1 - primary default WAN (Static IP) - Tier1
WAN2 - backup WAN (Static IP) - Tier 2
LAN - Local network
System\Routing\Gateway Groups\Edit GW_FAILOVER
Tier1 - WAN1
Tier2 - WAN2
Trigger Level Packet Loss or High Latency
All work perfect if :
- I unplug network cable WAN1
- Electricity fails on provider switch WAN1
- As an experiment, I put a switch in the gap . If unplug network cable from provider side, also all work. I wanted to see how pfsene responds if the link remains and the internet goes down.
But if the main (WAN1) provider fails the network core - switching providers does not work. Also WAN2 gateway also becomes unavailable. If unplug WAN1 , WAN2 becomes available.
In these moments, the ping gives incomprehensible things
user@User-PC:~$ ping GATEWAY_IP PING GATEWAY_IP (GATEWAY_IP) 56(84) bytes of data. From 220.127.116.11 icmp_seq=1 Time to live exceeded From 18.104.22.168 icmp_seq=2 Time to live exceeded From 22.214.171.124 icmp_seq=3 Time to live exceeded From 126.96.36.199 icmp_seq=4 Time to live exceeded From 188.8.131.52 icmp_seq=5 Time to live exceeded From 184.108.40.206 icmp_seq=6 Time to live exceeded From 220.127.116.11 icmp_seq=7 Time to live exceeded From 18.104.22.168 icmp_seq=8 Time to live exceeded ^C --- GATEWAY_IP ping statistics --- 8 packets transmitted, 0 received, +8 errors, 100% packet loss, time 7010ms
How to make the switching of providers work out successfully at these moments?

Hello there! I'm sorry but your words aren't as clear as they should be for getting help back on your issue. Thus if you can make a diagram would be much better. Also as far as I've grasped from your post, I would like to suggest switching the mode of fail over from "packet lost" to "member goes down" and observe the issue. Let's see what you will get back.
