proxmox and wlan how should the interfaces file look like?

[saeft_3004]

Hello,

I want to use proxmox over wlan on a NUC8i3. How do I have to configure the file interfaces for this to work?

With this interfaces file I have access via LAN (192.168.178.110) and via WLAN (192.168.178.104) to the proxmox web interface. But if I unplug the LAN plug then proxmox is no longer accessible via LAN and WLAN.

Here the current interfaces file:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
    address  192.168.178.110
    netmask  255.255.255.0
    gateway  192.168.178.1 
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0

auto wlp0s20f3
iface wlp0s20f3 inet dhcp
    wpa-ssid Krip..............
    wpa-psk c8e8...................

Here the output of ifconfig:

I would be very happy if you could help me. Many thanks in advance.

Good Morning,

does any one of you have an idea? I found the following:


LAN enabled and WLAN disabled:

LAN: NUC8i3 -> Powerline -> Fritzbox 7490 192.168.178.110 1C: 69: 7A: 02: 61: 91


LAN and WLAN enabled:

LAN: NUC8i3 -> Powerline -> Fritzbox 7490 192.168.178.104 1C: 69: 7A: 02: 61: 91

WLAN: NUC8i3 -> Fritzbox 4040 Access point 192.168.178.104 D0: C6: 37: CB: 4A: 12 -> Fritzbox 7490


LAN disabled and WLAN enabled:

No access to the web interfaces



If WLAN is activated then changes in the Fritzbox 7490 the LAN IP of 192.168.178.110 on 192.168.178.104 ?! The web interface is still accessible with the IP 192.168.178.110.

would it be better if I use wpa_supplicant instead of interfaces?
