Overview

Wireguard gained a lot popularity and attention when it went into Linux kernel in March 2020. And pure coincidence or not, 1 month later, Wireguard made its way through ubuntu 20.04 LTS. Csaba MATE, freeRtr maintainer took "the Taurus by his horns" (sorry for the pure French translation of the proverb (smile)) and in turn, he added Wireguard support into freeRtr few months later ...

Tip
titleRARE validated design: [ SOHO #009 ] - key take-away

In this example the key take-away are:

  • Wireguard configuration is simple
  • We used ubuntu 20.04 but of course you can enabled Wireguard with any host supporting Wireguard protocol
  • IPv6 is used here. But of course IPv4 is also available (wink)
  • Last but not least do not forget to export VRF and Wireguard tunnel interface in "server p4lang p4" should you run RARE/freeRtr with a dedicated dataplane (p4emu, dpdk or P4)

This is a pretty unique freeRouter feature ! Are you aware of any other router able to set up a Wireguard VPN ?
