Networking between proxmox host and windows 7 real PC

Question

Deploying working environment for business purposes I've installed proxmox. I've connected windows 7 to proxmox host directly without utilizing any switch or router. Windows 7 has access to the internet. Proxmox host does not have direct access to the internet. It could be connected through a router in the future to be accessed by its public IP.

I need to configure network between windows 7 and proxmox to be able to develop, deploy and run automated tests on VMs.

Network address with Internet access is: 192.168.1.0 Network between proxmox and windows 7 is: 192.168.0.0

Windows 7 is configured as a gateway in my case with IP address: 192.168.0.1

To get access to my home network I've reconfigured /etc/network/interfaces.new file:

auto lo
iface lo inet loopback

iface wlx70f11c0e99bd inet dhcp
    wpa-ssid MyHuaweiRouterSSID
    wpa-psk MySecret

auto enp0s25
iface enp0s25 inet static
    address 192.168.0.21
    netmask 255.255.255.0
    gateway 192.168.0.1

auto vmbr0
iface vmbr0 inet static
    address 192.168.0.20
    netmask 255.255.255.0
    gateway 192.168.0.1
    bridge_ports enp0s25
    bridge_stp off
    bridge_fd 0

After PC's rebooting the interfaces enp0s25 and vimbr0 are UP but I could not ping 192.168.0.1 - Destination Host Unreachable

So, I could not connect these two machines together. Please help me to consider what I've missed.

I was able to connect these two PCs by changing network configuration in /etc/network/interfaces.new.

auto lo
iface lo inet loopback

iface wlx70f11c0e99bd inet dhcp
    wpa-ssid MyHuaweiRouterSSID
    wpa-psk MySecret

auto enp0s25
iface enp0s25 inet static
    address 192.168.0.21
    netmask 255.255.255.0
    gateway 192.168.0.1

auto vmbr0
iface vmbr0 inet static
    address 192.168.0.20
    netmask 255.255.255.0
    bridge_ports none
    bridge_stp off
    bridge_fd 0

Edited. After trying to bridge vmbr0 with enp0s25 adapter changing bridge_ports enp0s25 to bridge_ports enp0s25, network failed to work. So on Windows PC I've created bridge with wi-fi adapter that looks into internet and ethernet adapter that looks at proxmox PC. I was trying different configurations with ip addresses, gateways and adapters but after that I've just reconfigured network on proxmox to:

auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
        address  192.168.1.21
        netmask  255.255.255.0
        gateway  192.168.1.1
        bridge-ports enp0s25
        bridge-stp off
        bridge-fd 0

removing enp0s25 configuration from config file at all. It resolved the issue. However, ifconfig shows:
