Product Overview

VyOS is an open-source network OS based on GNU/Linux that provides a unified management interface for all functions like traditional hardware routers.

It runs on bare metal as well as all major hypervisors and cloud platforms, so you can use the same OS everywhere and connect your on-premises networks with cloud sites without the limitations and costs of vendor-specific VPN solutions, or you can build inexpensive remote access VPN for your remote workers.

VyOS includes everything you expect from a router:

  • Routing protocols (BGP, OSPF, RIP)
  • Policy-based and multipath routing
  • VPN and tunneling protocols (IPsec, VTI, L2TP, OpenVPN, Wireguard, GRE, IPIP, SIT, VXLAN, L2TPv3)
  • Security features (interface and zone-based firewall)
  • NAT
  • High availability (VRRP, connection table synchronization)
  • QoS, NetFlow and sFlow traffic accounting

Image-based update, stateful CLI with commit and rollback capabilities, and built-in config versioning and archiving provide simple and reliable system management.

Built-in Saltstack integration and official Ansible module allow automating configuration workflow. For custom automation solutions, an HTTP API is available.


  • Advanced routing capabilities with modern protocols like BGP, OSPFv2/v3, Policy Based Routing
  • Various types of VPN - IPSec, VTI over IPSec, GRE over IPSec, OpenVPN, WireGuard
  • Stateful firewall, Zone-Based Firewall, NAT

Editor Details

VyOS is an open source project and was started in late 2013 as a community fork of the GPL portions of Vyatta Core 6.6R1 with the goal of maintaining a free and open source network operating system in response to the decision to discontinue the community edition of Vyatta. VyOS is primarily based on Debian GNU/Linux and the “FRRouting” routing engine. Its configuration syntax and Command-Line Interface are loosely derived from Juniper JUNOS as modelled by the XORP project, which was the original routing engine for Vyatta.

Some of the VyOS maintainers (Daniil Baturin, Yuriy Andamasov, Santiago Blanquet Bru De Dala) founded the company “Sentrium S.L.”, which can be basically thought as “the company behind VyOS”. Sentrium is also the company who provides support and consulting services specifically for VyOS.

Login via the CLI is possible using username “vyos” and the selected SSH key.

It is in the responsibility of the customer to protect administrative access (interface ports 22) using security groups, so that only intended people can access it.
