No internet access on windows VM with Local IP on Hetzner Dedicated Server

[pksh71]

Hi
I am trying to run a windows 7 virtual Machines with Local IP on Hetzner Dedicated Server with Internet access.
But my windows VM has no internet acess.

My Network Configurations area as follows:


### Hetzner Online GmbH installimage

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback
iface lo inet6 loopback

auto eno1
iface eno1 inet static
address 144.76.96.23
netmask 255.255.255.224
gateway 144.76.96.1
# route 144.76.96.0/27 via 144.76.96.1
up route add -net 144.76.96.0 netmask 255.255.255.224 gw 144.76.96.1 dev eno1

iface eno1 inet6 static
address 2a01:4f8:192:3116::2
netmask 64
gateway fe80::1

auto vmbr0
iface vmbr0 inet static
address 144.76.96.23
netmask 255.255.255.255
bridge_ports none

iface vmbr0 inet6 static

auto vmbr1
iface vmbr1 inet static
address 10.10.10.1
netmask 255.255.255.0

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

Don't know where the VM's virtual NIC is assigned to - probably vmbr1 (it should be). Then the question is what is vmbr0 good for? Note address 144.76.96.23 is defined twice, the assignment to vmbr0 is u useless ( as well as "up route add -net 144.76.96.0 netmask 255.255.255.224 gw 144.76.96.1 dev eno1") and should have no effect but it may have a negative impact to routing.
