How to connect to the internet from a virtual machine (proxmox)?

Question

linux

Installed windows 7 using proxmox , help me set up the network ( internet connection ).
Now it looks like this:

I created bond0 according to the instructions - https://www.proxmox.com/en/training/video-tutorial...
I read the information on different sites, I'm sure that the answer is here pve.proxmox.com/wiki/Network_Model , but due to its lack of competence, it still does not work.
Something tells me that this is the solution:

Masquerading (NAT)

In some cases you may want to use private IPs behind your Proxmox host's true IP, and masquerade the traffic using NAT:
auto vmbr0
iface vmbr0 inet static
        address  10.10.10.1
        netmask  255.255.255.0
        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 '10.10.10.0/24' -o eth0 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o eth0 -j MASQUERADE

Help apply it.
