iface enp2s0f1 inet manual

auto vmbr0
iface vmbr0 inet static
    address  public_ip
    netmask  255.255.255.0
    gateway  100.64.1.9
    bridge-ports enp2s0f0
    bridge-stp off
    bridge-fd 0

auto vmbr1
iface vmbr1 inet static
    address  10.10.10.254
    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 vmbr0 -j MASQUERADE
        post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o vmbr0 -j MASQUERADE
