As an example: some people might be using the offerings from Microsoft or Amazon, whilst other people might be running a VM with a VPS somewhere and hosting their apps like Homeassistant, OpenHAB, Node-Red etc there.

I wanted to know if you do something like this, and what might be the downsides to doing something like this.

Thanks!

    Tailnet appears to be Tailscale which is Wireguard underneath. This means it operates at layer 3 (IP). However a bunch of smart home stuff (mDNS, WoL, etc) all depend on layer 2 connectivity (same subnet).

    That means some stuff won’t work correctly.

      I see. Could you give me a few more examples on what could break if I go forward with this? Will I still need to consider multicast DNS if my DNS server is on-prem (Pi-Hole + Unbound)?

      I remember that it was not possible to route multicast traffic through IPSec earlier, which is why people used to opt for GRE-over-IPSec. But just as IPSec supports multicast traffic now, doesn’t Wireguard too? Or am I missing something important as to why this is not supported?
