How do I put the home server online

Step by step to the Linux web admin

Bring home servers to the Internet

Devices in your local network are protected from access from the Internet by the firewall. You must therefore set up port forwarding on your Linux PC in your DSL router. To do this, look for keywords such as "port forwarding" or "shares" in the router configuration. With the Fritzbox you will find the settings under "Internet -> Approvals" on the "Port sharing" tab. Configure the router to forward requests on port 80 (HTTP) to your server.

The server can then already be reached via the Internet at the external IP address of the DSL router. However, since the IP address of the DSL router usually changes every 24 hours, this is not particularly convenient. Some providers also offer a fixed IP address for a fee. Dynamic DNS services are a free alternative. Here you get a fixed address in the form of a sub-domain for your changing IP, for example meinaddresse.dyndnsangebote.xx. Most routers can be configured in such a way that they automatically inform the desired Dyn-DNS service of the new IP address after each Internet dial-in.

If you prefer an individual web address, you can register it with a web host for just a few euro cents per month. The hoster then ensures that your own domain is automatically forwarded to the IP address or the web address at which your server can be reached.

Tip: Fritzbox users can register for free at www.myfritz.net and then receive their own fritz.net URL. Shares for other devices can be configured via the Fritzbox interface under "Internet -> MyFRITZ! -> MyFRITZ! Shares".
