I changed the interface in /etc/network/interfaces, now it has an IP on my home network. But something is messed up in the config. Im not a networking expert nor deep einough in IT to be able to figure out what could be the problem. Here is my current /etc/network/interfaces

The "iface ens1 inet static" stanza can not have a "bridge_ports xyz" ;-)

Which is your actual interface? eno0 or ens1? Check with "ip add show". If it is ens1 try this to create a bridge:

Code:
iface ens1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.57/24
        gateway 192.168.1.1
        bridge-ports ens1
        bridge-stp off
        bridge-fd 0

I've tried the config that you suggested, above. Luckily I still able to reach my proxmox instance, but the network bridge still doens't show up. I did a "systemctl restart networking" and a "service pveproxy restart" before trying. EDIT: I did a full reboot, still didn't show up :/

Ah nevermind, I didn't save it correctly, after the restart, I pasted it again, and pressed a ctrl+s in nano. It's fine now, sorry. Thank you for your help ^^
