Intra communication among servers under Argo Tunnels

Hi guys, I’m experimenting with Argo Tunnels and it’s working lie a charm. But now I’d like to connect all my servers in cluster by using a TCO/IP protocol. How can I do that?

Normally I’d think on using a VPN that connects all the servers, but I thought there could be a smarter way under CloudFlare. Am I right?

I also though to create a new tunnel “cluster” used exclusively by the cluster protocol, but the issue is that Argo doesn’t allow TCP connections (only HTTP and SSH AFAIK).

Any idea? Thanks, Luca
