@homegrown Hosting my iwn Nextcloud server I was trying to set up an additional Matrix server on a different hardware. I could not solve the issue of having two servers behind one external IP. Even with a static IPv4 address. IMHO this is some kind of essential to understand those concepts to host several servers behind one IP.
I would love to learn some mire about how to... . And I am sure that others have the same issue, thus preventing them from implementation.
@xphera @homegrown Thanks. I know. But I was not able to configure that. I mainly found basic explanations (like you linked) or technical documentation of e.g. Apache. But nothing in between like a tutorial.
@aircan
Sorry, I'm not sure I can help :/
I think that's more a question for system administrators?
I'm trying to help people using managed hosting services.
