- PFI-UDMSE port 6 override: native nh3-mgmt, tagged VLANs blocked (was
forward all / native default). Reservation nh3-pve-amt -> 10.100.250.61.
- nh3-pve: arp_ignore=8 / arp_announce=2 on enp88s0 (now on vmbr0's untagged
L2) so the host never answers ARP for 10.100.250.60 with the AMT port's MAC.
- DNS nh3-pve-amt.nh3.internal -> 10.100.250.61.
- Homepage: NH3-PVE-AMT card under Infra - NH3 (no siteMonitor/ping: AMT drops
ICMP and its legacy-renegotiation TLS fails Homepage's fetch).
- AMT keeps its old 10.100.0.151 lease until rebind/expiry (~1920-2224 PT
2026-09-26); it does not re-DHCP on a VLAN change or link drop (measured).
