Linux Networking

The Linux kernel includes a full-featured networking stack that can replace proprietary network appliances in many scenarios. Bridges, VLANs, bonding, nftables firewalling, policy routing, traffic control: Linux handles it all natively, without additional software or licensing.

Replace proprietary appliances

Managed switches, commercial firewalls, and dedicated routing hardware all have open-source equivalents in the Linux networking stack. For companies building sovereign infrastructure, this means fewer vendor dependencies, lower costs, and complete visibility into how your network operates.

nftables and modern firewalling

nftables is the successor to iptables and provides a clean, unified framework for packet filtering, NAT, and traffic classification on Linux. It is more expressive, more efficient, and easier to manage at scale than its predecessor.
