External access in complicated way

I’m looking a way to enable access to Nextcloud server from the Internet but without public IP and without port redirecting on the router. Technically i see it as public server/service (owned by me) to which Nextloud server connects (creates some kind of tunnel?). And this server redirects traffic from/to Nextcloud (in a secure way). Is there any software avaiable somewhere? To be honest i don’t knot what to search, so any help will be appreciated.
TIA

You can use a VPN for that.

Thanks for tip. I will have to check if it will scale with dozens (or hundreds) of Nextcloud servers.
