I would like to be able to terminate all TCP sessions to a GCP VM in a few seconds, i.e. drop established connections, and thus the stateful firewall rules do not do the job.
I am able to do this on AWS (via the NACL feature) and Azure (via a null route). On GCP I am able to do it with IPv4 by use of address aliases, which is quite a bit different than the other implementations, but seems to work. However, I don't see a viable way to achieve this if using IPv6. Is there a way?
