Run a Valheim dedicated server using Docker. There are plenty of other solutions out there that has way more features than this. I wanted a bare minimum setup.
The image can be found at:
docker pull ghcr.io/ekman/valheim:1View the example docker-compose.yml file for indications on how to install, configure and run this.
Open UDP ports 2456-2458 on your router and forward them to the hosting server/computer.
Mount all these volumes to your host.
