Not ubiquiti's doing but this repo has pre-built kernel modules of wireguard and vyatta integration for I think most of the edgerouter series: https://github.com/WireGuard/wireguard-vyatta-ubnt

I haven't updated/tested in awhile but last I remember I was seeing 800+ mbit/s on my dinky mips ER-X. Pretty amazing and easy to use.

Can confirm, way back I wrote a small guide on how to install and configure Wireguard on the ER-X (and other EdgeRouters), and to date this article is still by far the most read one: https://merlinscholz.name/post/wireguard-on-erx/

We built an Ansible role to install and configure Wireguard on EdgeOS. It works well on EdgeRouter Infinity ER-8-XG and EdgeRouter X.

This repo appears to use Lochnair's old builds, which are unmaintained/deprecated and replaced with the official ones linked to by GP.

Unfortunately 3rd party software installs are lost on updates, so you need to be local to the router before upgrading (or have a secondary VPN available).

Development of EdgeOS has really slowed down though, there hasnt been a stable firmware update in 6 months (and that was just a small hotfix).
