The device supports the use of WireGuard, but the setup is not pre-installed by default and requires manual configuration via the command line. Users report that it is possible to install WireGuard on the router and operate it as a VPN client or server, whereby corresponding configuration steps are required. For the EdgeRouter X SFP, there are instructions and examples on how to set up WireGuard, but this is not integrated as a plug-and-play function.
