Managing Wireguard is just one of Tailscale’s features.

It uses some UDP black magic fuckery to get through NAT and firewalls without having to open ports. Very useful if you’re behind CGNAT and/or your ISP is a dickhead and locks down the firewall on your router (this is why I use it; eat a dick, Vodafone). If the UDP fuckery is not available, it reverts to simple relay servers. The client can also advertise subnets and route to hosts on it. You could install the Tailscale client on OPNSense/pfSense/OpenWRT and access your entire home network through that one device.
