Unable to add Cloud NAT Gateway to existing Cloud Router

Google Cloud Compute Infrastructure
1

Hey,

I have an existing Cloud Router with a couple of BGP sessions associated, and I’d like to add a Cloud NAT Gateway to it. From what I can tell, this should be possible, but both via the web UI and the CLI, I get an error:

$ gcloud --project my-project compute routers nats create my-nat-gateway --router existing-cloud-router --nat-external-ip-pool my-static-ip --nat-all-subnet-ip-ranges --enable-logging --region europe-west1
ERROR: (gcloud.compute.routers.nats.create) HTTPError 400: Updating multiple Router features is currently unsupported.

I get no hits for this on Google, so I’m wondering if the Cloud Router has pending changes somewhere that I can’t see (no clues from describing it via the CLI), it’s otherwise broken, or something along those lines.

Has anyone come across this before?

Thanks,

Ben

Just as an update, I’ve tried to do the same thing on a different Cloud Router in a different project altogether, and I get the same error message. I’m assuming that means that the router itself isn’t at fault, but I’m still no closer to figuring out the problem :thinking:
