I have a VLAN configuration which i wish to add to Debian 11 Debian GNU/Linux 11 (bullseye) but no success. I followed the tutorial on internet. Although VLAN is added but i can not ping the VLAN address. Surperisingly i also experimented to add VLAN on Ubuntu server (Ubuntu 22.04.2 LTS) it worked flawlessly and the ping was also working.
On Debian 11 i tired:
Code:
#apt install vlan
Reading package lists... Done

vlan is already the newest version (2.0.5).

Moreover as soon as VLAN is added i can also not ping the wlan0 IP.
On ubuntu serve i added the VLAN by editing netplan file and it working. If it is interesting my hardware is Raspberry pi 4.
