mwan VS wireguard-vyatta-ubnt

It is.

Multi-wan is easier with appliances. I used pfSense over the last 12 years or so with multi-wan on and off (currently off). I've run pfSense in a kvm VM, and you can do multi-wan with this. Though I generally recommend dedicated NICs for the WANs and LAN.

I've looked at the linux based appliances (as late as last week) and only clearos supported multi-wan. I could be wrong (I'd like to be as pfSense/OPNsense are FreeBSD based, and that comes with, sadly, huge amounts of baggage, limited hardware support, etc.). I'll likely be looking at that package as a potential replacement for the pfSense system, though if clearos can't handle what I need, OPNsense is like pfSense, but with far less baggage.

If you don't mind tinkering, you might be able to use mwan3[1].

If you prefer OpenWRT, you can look at running it in a VM[2] along with mwan3.

Joining serverless environments like AWS Lambda to a mesh network has traditionally been difficult because you can't directly access the network interfaces on the hosts that run your functions. The NetBird netstack mode addresses this by providing a simulated TUN device and a SOCKS5 proxy that targets that device. This allows your Lambda function to access other services in your NetBird network via the proxy.

NetBird simplifies Kubernetes access with its zero-configuration approach, leveraging WireGuard's simplicity and strength. It seamlessly integrates with various tools, offering transparency and high reliability as an open source solution.

As for remote access, you will need another computer to install tailscale or wireguard vpn to access your local devices https://www.youtube.com/watch?v=AkKz7Vza1rw and the official docs for up to date advice https://www.wireguard.com/ this doesn't require much to run, you can use any old family computer or some old quad core 2nd-4th gen intel desktop for 30 bucks off facebook marketplace. You can also use that same computer to run klipper if you install proxmox and have two separate linux virtual machines.

Um modo mais avançado de se proteger é utilizando protocolos de VPN mais modernos, como o WireGuard. Muitos provedores de VPN oferecem suporte a este protocolo, que além de muito simples de usar e além do mais é open source.

here u find out how wireguard works https://www.wireguard.com/

WireGuard is a VPN protocol developed several years ago which is exremely fast, lightweight, and uses state-of-the art cryptography. Its performance blows legacy VPN's out of the water.

Try vanilla. It solved all my problems bar none.
