I'm fighting with the following problem.
- I got an Hetzner dedicated Server with multiple additional IPs which I want to use for KVM VMs. (MainIP = 1.1.1.1, First additional IP: 2.2.2.2)
- Before my server was running Ubuntu 16.04 and acts as a router for the VMs. So every VM had its own public IPv4 and the gateway was the host itself. This was working very well!
I followed this:
https://wiki.hetzner.de/index.php/Netzkonfiguration_CentOS
and
https://wiki.hetzner.de/index.php/KVM_mit_Nutzung_aller_IPs_aus_Subnetz
How can I do that with Fedora 32 using Firewalld, Nftables and NetworkManager enabled?
I tried following the guide and adapting the commands for Fedora. At the moment I got one VM running on br0 Host-Device.
