i have a setup with a firewall pair and multiple gateways in a group. tier1 is a single gateway monitored with 1.1.1.1, other gateways use similar setups but different ping ips

i recently added a network interface and restarted the master firewall services using rc.reload_all

the carp vips switched back and forth as expected : the statuses on both firewalls were consistent.

nevertheless the default gateway was deleted and only came up again after is manually switched to one of the gateways

i switched back to the group without further issue

i could see a few complaints from dpinger stating it detected over 20% packet loss but that was only punctual and i assume due to carp

in the general log, there is no log from /system_gateway_groups.php between the carp failover and the moment i switched thing back manually

any ideas regarding how to debug further ?

any way to instruct pfsense to keep the first gateway active at all times ?

anyone knows which component deals with the gateway changes ?

if i remove all routes, will pfsense toy with my configuration ? i have existing working scripts for gateway failover and can use them

thanks for your time
