Since my old Fritzbox I used with openwrt and wireguard went to oblivion I want to make use of wiregiard on my xpenology (HP54NL), too.
The docker solution of https://github.com/runfalk/synology-wireguard sounds promising. But since it is a bit behind my horizon I would like to know what you think about it and if you got things nicely running before I start digging into it.
