Tunnelbroker setup in a small VM

[rattila]

Hi,

How can I enable protocol 41 (6to4) on firewall? Is that possible? I read somewhere protocol 41 is not supported. It was enabled and I couldn't see any traffic in the log and no RX packets on the interface.

Of course I know there is dual stack VPC possibilities but my VM is very small (e2-micro). 

TIA,

Hi @rattila ,

GCP does not support enabling or allowing Protocol in its firewall rules. 

If Protocol 41 is required for your use case or specific purposes, you might need to explore alternative solutions beyond GCP. This could involve setting up tunnels using external resources or opting for a different cloud provider that offers support for IPv6 tunneling.
