i have installed Devstack without neutron on a Hetzner Server. The Problem is, my Windows instance doesnt reach the Internet. i googled and i found out, that hetzner blocks Every VM that doesn't have the following MAC-Address 54:52:00:XX:XX:XX ... how can i change or see what kind of MAC my Instance have?

I have only a single physiscal network-adapter: eth0 and by default created by devstack br100 which is used for the instances for internal communication.

i can ping my Instance from Outside, but i cant reach the Internet inside the VM.

Steps i made:

nova interface-list 8d0fd562-bec2-47b0-9162-7a7239fbdd55
ERROR (HTTPNotImplemented): Network driver does not support this function. (HTTP 501) (Request-ID: req-1759ddab-157a-4d26-b63f-9f01aaa57260)

opened the ports for ssh connection
nova secgroup-add-rule default tcp 3389 3389 

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -t nat -A POSTROUTING -o br100 -j MASQUERADE
both didnt worked

serveral settings in the sysctl. changed the sysctl settings to forwaring ipv4 avoid redirecting icmp

i think the real issue is that the MAC-Address will be blocked

Can somebody help me how to figure this issue? if i would need to install neutron, what should i have to do to correct route the traffic?
