Ping is failing from the VM to the vnet1 interface 192.168.52.1. Check your VM Hardware configuration. Check the Network Device and ensure it is bridged to vnet1. My guess is the Network Device is bridged to vmbr0, which is a network blackhole.
Can I use the default vmbr0 to replace vnet1 as the bridge, I have tried this, but it doesn't work, I wonder why it doesn't work, but vnet1 can work, thank you very much
No. You can't bridge the physical wifi adapter (unless your wifi access point supports WDS mode). That's why I wrote the Tutorial.
Got the host connected to internet via Wifi. Stuck on getting guest Windows VM connected to internet.
I added vnet1 as network device to the Windows VM.
But when I tried to do
on Windows, I get
response.
My '/etc/network/interfaces' is same as original post except router ip(gateway) is 192.168.0.1 and address for vmbr0 is 192.168.0.200.
Any advice would be helpful.
Update: Realized I need to give interface number. It gave OK after that but still no internet.
I added vnet1 as network device to the Windows VM.
But when I tried to do
Code:
route add 192.168.3.0 MASK 255.255.255.0 192.168.0.1
Code:
The route addition failed: Element not found.My '/etc/network/interfaces' is same as original post except router ip(gateway) is 192.168.0.1 and address for vmbr0 is 192.168.0.200.

You do not need to manually add routes to VM's. Static routes only need to be added to hosts on your local network so they can access hosts on the vnet1 subnet. For your Windows VM, simply configure the Gateway setting to use the IP address of the vnet1 interface of the Proxmox server.
I set the Windows VM like this:
Windows Diagnosis tool says:
(I hope gateway IP here should not be actual router IP(i.e, 192.168.0.1). I tried that and Windows Network Diagnostic thing said 'Unable to access DNS server'. Pings didn't work so DNS isn't the only issue with 192.168.0.1)
And on my host/Proxmox:
Code:
> cat /etc/network/interfaces
auto lo
iface lo inet loopback
iface enp1s0 inet manual
auto wlp2s0
iface wlp2s0 inet static
address 192.168.0.100/24

# netmask 255.255.255.0
auto vmbr0
iface vmbr0 inet static
address 192.168.0.200/24
gateway 192.168.0.1
bridge-ports enp1s0

bridge-fd 0
auto vnet1

source /etc/network/interfaces.d/*The screenshot shows you have assigned Windows the IP address of 192.168.3.0. That is not a valid IP address for the configuration you're using. Your vnet1 subnet is 192.168.3.0/24. You cannot assign an IP address of 192.168.3.0 based on the subnet range you have chosen. Assign your Windows host an address between 192.168.3.2 - 192.168.3.254. You cannot assign the Windows host the 192.168.3.1 address because that is in use by the Proxmox vnet1 interface.
