This is a router and firewall network configuration system. It is specific to the 2.4.x and 2.6.x kernel series. This system is in production use, even though this is an experimental version. [...] DON'T use this on a pure server - it is VERY useful for a Virtual Machine server with complex networking needs. This is because of its comprehensive network configuration capabilities. Thus it is a tempting replacement when you have to rip out NetworkManager on a server. That sounds pretty terrifying to me. I'm surprised it works *at all* with a Debian 11 (or higher? you didn't say what you *are* running, only what you're *not* running) kernel.
