Vyos is my go-to for router/firewall distributions. It's pretty much a swiss army knife of router/firewalls thanks to the extensive feature list.

Vyos is a highly versatile networking solution that can be deployed on a range of hardware, from low-powered mini PCs for basic home routing to high-performance enterprise servers and virtual machines. This flexibility allows it to cater to a wide variety of users, regardless of their environment or specific needs.

Vyos supports advanced routing topologies and a comprehensive range of routing protocols. It also offers robust VPN support, including protocols like WireGuard, IPSec, and OpenVPN.

Recent versions have integrated HAProxy, which has proven to be extremely useful. The firewall configuration is intuitive, easy to manage, and effective.

By far, the command-line interface is my favourite feature of Vyos. It makes setting up firewall rules, NAT rules, QoS rules, site-to-site, or roadwarrior VPNs extremely easy to implement. I haven't seen any other router/firewall distribution with such a versatile and easy-to-use command-line interface.

Vyos also has an API which can be used to configure Vyos using tools like Terraform or Ansible.

The documentation is generally excellent, featuring many examples. While some sections may occasionally be slightly out of date, it’s usually easy to adapt them to newer versions with minor command adjustments.

I haven't had to talk to customer support directly, but I have reported bugs via their bug tracker, all of which have been promptly resolved. Review collected by and hosted on G2.com.

I can't really think of anything I dislike about VyOS. I've been able to do everything I've wanted to do in VyOS pretty easily.

If I had to be extremely picky the only thing I would say is, even though there is VyOS Stream coming soon, it would be nice if there were something like a lower cost home user/self-service/hobbyist license option to get access to the normal LTS release. Though with Stream coming soon, and with the nightly builds being pretty stable it's not a massive concern, just something that might be a good option as some users (including me!) would prefer to run LTS at home to match what we have in our "production" environments.

Works great with small applicances, as VM, with great performance. Its ability to have advanced routing, switching, multicast-routig, vpn with ipsec is outstanding. documentation is ok but in many points not complete

Update (20240818) - as I am testing version 1.4.0 I also see that the documentation is getting better and a lot of effort is put into scripts to automatically convert older configurations into compatible ones for the newer version. Review collected by and hosted on G2.com.

I missed most the option to use eliptic curves in ipsec connections (rsa suported and with "bad hack" ecdsa is also possible) and that the documentation is not complete and leave a lot of questions open (when you dive into more advanced areas), i also would like to have IPv6 to be able to turn off (all option available do not work), and i do not like that they removed tshark from recent version - it was not perfect as it has display issued when debugging vpn interfaces (would be helpfull if the output would have stated which point in the precess queue the packet displayed is from - e.g. you see non encrypted packages on the tunnel interface - but measuring direct on an external device everything is ok). thats it for now - please do not get the impression there are more bad than good thing - i really love VyOS

Update (20240818) - I am in the evaluation phase of VyOS Version 1.4.0 and I have to say that version is a major step in the right direction. My beloved eliptic curves (ECDSA) are supported out of the box (no patch needed anymore) for public key materials, logging of IPsec is much better, and the new firewall implementation is now able to control any packet flow originating from VyOS (was not true for older versions). My IPv6 problem can be addressed now with the appropriate firewall rules.

I also found an IGMP handling bug in the version 1.3.6, which could be found and fixed with the superb help of the VyOS support. The time to fix was incredible fast compared to traditional support I used in the past for other network software/hardware like Cisco or HPE. I am really thankful for that.

A simple CLI that allows you to view complete configurations.

All the necessary features for Internet connectivity in an affordable hardware device.

An accessible Debian-Linux base that allows you to adapt the equipment to your needs.

A lot of services and functionalities with low cost.

Very fast on little hardware.

Good for virtual environments. Review collected by and hosted on G2.com.

Logging and monitoring functionalities are not up to par with commercial solutions such as Cisco IOS or Juniper.

Limited IP SLA and floating routes.

Scripting know-how needed for advanced set-up Review collected by and hosted on G2.com.

We find VyOS very easy to use, the CLI is very intuitive and particularly familiar if you come from a Juniper background. It's very easy to get installed and you can build up configuration slowly without tying yourself up in knots, it'll give you useful messages when things aren't working. Although we don't have a support contract ourselves, we've found the VyOS developers and staff very supportive and welcoming. We've used VyOS ever it first started as a project (moving away from Vyatta 6.1), so we've been using either Vytatta or VyOS since 2010 and have never stopped. The fact that it has a built in PPPoE server makes it very easy to allow other routers (e.g. OpenWRT) to sit behind VyOS and get a public IP. Review collected by and hosted on G2.com.

I can't really think of any. Obviously from time to time you might wish it had an extra feature or two, but nothing that you can't suggest or contribute yourself... as it's an open source project. Review collected by and hosted on G2.com.
