Best Virtual Routers for Linux of 2024

Simple packet filters will soon be a thing of history. Even the open-source community is moving toward Next-Generation Firewalls. OPNsense, a leader in intrusion detection, web filtering and anti-virus, is also a leading player. No network is too small to be targeted by an attacker. Even home networks, washing machine, and smartwatches, are at risk and require a safe environment. Firewalls are an important part of the security concept. They protect computers and networks from known and unknown threats. A firewall will offer the best protection if it is easy to use, has well-known functions, and is placed in the right place. OPNsense takes on the challenge of meeting these criteria and does so in different ways. This book is an ideal companion to help you understand, install and set up an OPNsense Firewall.

Open source software and a universal router are key to democratizing the way we access networks. VyOS' vision is to revolutionize how we access networks, so that everyone can build the solutions they have always wanted, without limitations, restrictions, or prohibitive prices. We believe that internet access is just as important to human development as food, water, air, and healthcare. VyOS was founded by engineers for engineers. It is an open-source software company that makes it possible to access networks without restrictions or prohibitive fees. Through our open-source software and virtual platforms, we do this as VyOS. Stateful firewalls, zone based firewall, all types source and destination NAT (one-to-one, one-to many, many to many). For auditing, creating customized images and contributing, everyone has access to the entire codebase and build toolchain.
