It took me couple of hours (trial-and-error) to find out how I could connect my Zeus wallet to my lightning node using Tailscale. The Zeus documentation don't provide me the info as I'm not using on of the described node platforms there.
On my blog I've written a short explanation how I connected my Zeus wallet using Tailscale instead of Tor. The Tor connection was always very slow. Opening Zeus to send or receive a payment was always unworkable. Now connected using Tailscale I'm able to use my Zeus wallet loads instant without the hassle waiting for an active connection.

Basically it was just running this command on my node and scan the QR code with Zeus:
lndconnect --host=<your_private_ip_address_from_tailscale> --port=8080 --nocert
Hope this can help anybody out in the future who is not using one of node platforms described in the Zeus docs
