[SOLVED] PPPoE packets dropped?

[fragtion]

I am trying to dial PPPoE from a guest VM, but I don't see the concentrator when using the bridged setup?? The only thing that works for me is to passthrough a real NIC to the VM. Doesn't matter which VM OS I use (tried linux, windows, and mikrotik), or virtual NIC type (tried E1000 and Realtek)

Yet on the proxmox host, I can successfully query the concentrator using pppoe-discovery -I vmbr0 / pppoe-discovery -I vmbr1

I have disabled all firewalls. Why/where is PPPoE being blocked? Is there a bug here or something? I've spent hours on this. I'd really like to use vmbr1 for PPPoE... Please help! Running proxmox-ve_6.1-2.iso

Edit: Found the problem - in my case ISP was blocking proxmox automatically generated MACs. I generated other random MACs and assigned those to the VM interfaces and presto.
