Hi, guys. Like in the title. I have orangepi5 with some services like nextcloud or grafana. I would like to access to those instances from outside - but I don't want to open ports. Could you guys point me how can I achieve that? Do I need to set domain for home services? I have heard that people recommends cloudfare tunnel, but I think cloudfare tunnel does not work with subdomain like duckdns. Do I need to buy domain for my case? One more think, if I set this tunnel or maybe other solution- should I go with https (lets encrypt) solution? Thank You
