Ursache der „WireGuard reißt immer wieder ab"-Abrisse war NICHT die UniFi, sondern keepalived-Flapping im HA-Cluster: die VIP 89.163.205.100 (an der die UniFi-Site-to-Site hängt) wanderte bei ~17 VRRP-Wahlen/Tag zwischen utm-1/utm-2 → Tunnel-Abriss bei jeder Wahl. Drei Bugs: 1) Firewall ließ VRRP (IP-Proto 112) zwischen den Cluster-Peers NICHT zu (policy drop). Adverts überlebten nur via conntrack-Reverse-Matching → bei conntrack-Ablauf gedroppt → Peer promotet sich → Split-Brain. Fix: ruleset.nft.tpl erlaubt `ip/ip6 ... vrrp saddr @peer_ipv4/6`; firewall.go nimmt zusätzlich hb_src_ip/hb_peer_ip aus cluster_settings ins Peer-Set (deckt den Heartbeat-Pfad 169.254.0.x ab). 2) Kein nopreempt → erholter Node riss die VIP sofort zurück (Flap-Back); aggressiver gw-Check (fall 2 → 10s-Blip = Failover). Fix: keepalived.conf.tpl mit `nopreempt` in VI_1+VI_HB, chk_gateway fall 2→5; keepalived.go setzt State immer BACKUP (nopreempt wirkt nur in BACKUP), Priorität 200/100 aus pg_role bleibt → deckt sich mit „manuelles Promote". 3) keepalived-Boot-Race: Unit startete vor vlan500 (nur After=network-online) → „interface vlan500 doesn't exist" → permanenter CONFIG-Crash ohne Recovery (keepalived nach Reboot tot). Fix: postinst legt Drop-in mit After=/Wants=edgeguard-interfaces.service + Restart=on-failure an. Neuer Test internal/keepalived/keepalived_test.go (nopreempt/BACKUP/fall).
