How to enable mTLS authentication when using NGF?

[vazkarvishal]

How do I enable MTLS checks when using Gateway Fabric?

Nginx Ingress - MTLS settings

Is this a limitation that auth-tls annotations cannot be used on NGF?

Also found the below issues. Are these related and thus, can only be used by Nginx Ingress Controller?

Hey @vazkarvishal!

We currently don't have support for mTLS for client to NGF connections, nor NGF to the backend. The Gateway API sig has not yet finalized how mTLS should work, but for those issues you found above, we'll be pulling ahead the design they do have.

The last issue there is for enforcing mTLS between applications - a bit like a lightweight service mesh.

Which one were you looking for specifically?

There MAY be a way to enable this right now using our SnippetFilter, but that might be tough since we need a file that contains your certificates... I'll let a maintainer chime in here.
