Hi,
I upgraded to Proxmox 7 and averything seems to be ok.
Anyway, I ran the ip -c link command and I now see to new network items in the list:

Code: 
....
tap102i0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500

tap102i1: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500

They both have their own MAC address as well.

What are they for?
Thanks
 
The tap devices are created when a VM is started, for each added NIC one tap device.
This is the connection between the bridge and the VM.

Ok, but I didn't make any changes to my configuration and VMs, nor added new VMS. I haven't understood why there wasn't any TAP device in the list before I upgraded to Proxmox 7.
Thanks
 
Probably because you had no VM running?
They are only created on start of a VM and destroyed once the VM is shut down.

Same VM (pfsense) running at the startup before and after I upgraded to V7
 
You probably just didn't noticed them before. They also existed in PVE6.X and if your pfsense VM had network connectivity you definitly had them.
