Excellent appliance at fair price
We have been using VyOS for standard and dynamic (routed) VPNs, GRE tunneling, NAT, Firewall and it delivers everything with rock-solid stability. The CLI is very intuitive and easy to understand even if you have never used VyOS before (of course some networking background would be required). The price/performance ratio is perfect fit for hybrid dispersed environments, making the "journey to the cloud" more affordable and easier.
