Explore alternatives to border0 to unauthorized access to containerlab nodes over Internet

[hellt]

Since border0 doesn't allow unauthenticated access to the nodes it is challenging to expose lab nodes to the open internet if users wish so.

We have to explore alternatives, such as

ngrok

seems to be exactly what we need

Tailscale funnel

Unfortunately it seems that funnel can't expose arbitrary TCP ports and is limited to HTTPS applications.

Cloudflare

TBD

Teleport

Requires a client to be authenticated, which is not ideal as we want to provide un-auth access.
