I have a Raspberry Pi and want to run various things (Internet pages, Minecraft server) on it, so it is important that it can be accessed externally. Can it be done somehow without a static IP, and if not, which VPN provider is good, and how can I install it on my Raspberry Pi?
A VPN provider operates a service in such a way that the VPN server is located somewhere in a data center. That doesn't really help you much.
You need a DynDNS service, which is free. I use dynv6.com, but I've also used no-ip.com and freedns.afraid.org. You don't have to set this up on the Pi, for IPv6 you can also set this up on most routers. They usually have support for some of these services.
Every time the router receives a new IP address, the router automatically reports this to the DynDNS service.
Check beforehand whether your internet connection uses DS Lite. If that is the case, you can't be reached via IPv4. Then you can only work with IPv6. There are also DynDNS clients that you can install on the Pi. It then reports its IPv6 address to the DynDNS service.
In any case, you have to configure the corresponding port forwarding in your router.
If you need to be reached via IPv4 and your connection uses DS Lite, you have to use a so-called tunnel broker. A search engine can help.
A web server and mc server is no problem for the latest generation pi (pi 4). Since you want mc server, it is worthwhile with min. Get 8GB of RAM.
if you want to access from outside and want it to be static. Are there free dyn-DNS providers, register there and create a host (e.g. Desired name.dyndns.org) you would have to configure your router by simply selecting the provider and entering the access data you had previously created. After a few minutes you can reach your router via the dyn-dns name.
then you only have to release the ports from the mc and web server from the pi to the router to the outside.
