I got two physical network cards in my proxmox machine, and both have a bridge interface to VM:s, that with lo means i see 5 instances under my node/network. If I log in to server via SSH, and use ifconfig or ip address it tells me that i got 17 nic:s. I have no idea where they are comming from or what they are doing but the do not show in GUI.

First network card i dont recognise from the list is tap100i0 followed by, tap101i0, tap107i0, fwbr107i0, fwpr107p0@fwbr107i0, fwln107i0@fwpr107p0, tap107i1, fwpr107p1@fwln107i1, fwln107i1@fwpr107p1.

Any idea what they are?
These are the interfaces automatically generated for your VMs/containers. They are managed automatically by PVE, so they are not displayed in the GUI.
Allright, thank you for the answer. Before last update I never came upon them, thats why i was not expecting to see alot of interfaces now all of a sudden :)
