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) and 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 upgrades
• stateful CLI with commit and rollback capabilities
• built-in config versioning and archiving provide simple and reliable system management.
