I have had a NAS running docker with various containers, but I just purchased a very cheep ubuntu running docker (managed via portainer) VPS over the cloud. My NAS CPU/RAM is fairly limited and I would like to offload some resources to this cloud instance. Is there any good documentation on establishing a VPN for local traffic to my network? I have Wireguard running on my Unifi UDM and I am thinking this is the first step for linking the virutal cloud server. Thanks!
