Yep, this may actually need more investigation, as I also had this issue on= a single PVE VM on my ArchLinux host. - definitely no duplicate mac addresses there - no MAC related firewall settings - network traffic *routed* off of a bridge on the host (so the final physic= al nic being an intel one should also not influence this) - works when disabling `bridge-vlan-aware` - still works when enabling vlan filtering via /sys after the fact - also works with MACAddressPolicy commented out *regardless* of `bridge-vl= an-aware`... Also tried using systemd-networkd for the bridge in place of ifupdown2. Same behavior when toggling `VLANFiltering` in the [Bridge] section... Also note that similar to manually enabling vlan filtering via /sys, simply= enabling `VLANFiltering` and restarting `systemd-networkd` does not actual= ly break it, only if I delete the bridge first and then let systemd-network= recreate it from scratch it'll be broken... Curious stuff...
