Not working connection forwarding from wlan to vmbr0

I've followed this setup guide, but I'm still having connection issues. It doesn't work.

Internet connection is not available within the virtual machine for both windows and linux.

I am attaching my config file.

auto lo
iface lo inet loopback

iface eno1 inet manual

auto wlo1
iface wlo1 inet dhcp
        wpa-ssid ssid
        wpa-psk pass

auto vmbr0
iface vmbr0 inet static
        bridge-ports none
        bridge-stp off
        bridge-fd 0

        post-up   echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up   iptables -t nat -A POSTROUTING -s '' -o wlo1 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '' -o wlo1 -j MASQUERADE
        post-up   iptables -t raw -I PREROUTING -i fwbr+ -j CT --zone 1
        post-down iptables -t raw -D PREROUTING -i fwbr+ -j CT --zone 1

I hope there is a way to solve this problem. I am ready to provide all additional information, if necessary.

Thanks in advance for encourage:)
WLAN isn't really supported on PVE. If you're determined to give it a shot, check out this page:

...but in general, the answer you're looking for is "get a cable" ;)
