I've created this little Debian11 Machine on my Proxmox Cluster (on KVMDebian11 Picture)
As you can see I've added one Network Inteface wich is bridged. Since I'm not using any kind of DHCP
I decided to configure the IP Adresses static. I'm only using IPv6 so I edited /etc/network/interfaces to the following (KVMDebian11Interfaces Picture).
Sadly after several reboots nothing changed and "ip addr" or "ip a" still shows me this output (KVMDebian11IPA Picture).
Its not taking any of my settings neither for eth0 nor for eth1. What am I doing wrong? I can't ping at any point so it seems to be unconfigured.
Resetting the config file and rebooting brought me the same "ip a" output.
