This guide assumes you have already e-mailed us at gatewaycoop@commoninternet.net (or gotten in touch with us another way) and we have sent you a link which contains the passwords you need (the tailscale authentication key, and the login details for the web admin of the gateway).
You need to have command line access on your server, either via SSH or via a screen adn keyboard.
Then run the following command to connect to the gateway (substituting in the correct tailscale authentication key that you received):
curl -fsSL https://tailscale.com/install.sh | sh && sudo tailscale up --auth-key=tskey-auth-youractualkeyhere
After that you should be able to confirm you are connected to tailscale by running:
sudo tailscale ip
This should return the private IP of your tailscale tunnel.
Then go to the web admin interface of the gateway https://g1.commoninternet.net/admin/ and log-in with the username and password that was also sent to you. Add your domain of choice to the gateway, and connect it with the private IP of your tailscale tunnel that you got in the previous step.
If you choose a domain which is a subdomain of commoninternet.net (e.g. myname.commoninternet), then things should already be working at this point.
If you choose to use your own domain name, you need to now go into your own DNS registrar, and create an A record to point your domain to the public IP address of the gateway: 143.244.213.108. This will cause requests to your domain to be sent to the gateway, which are then properly routed to your server via the tunnel.
At this point you should be able to access your home server through the gateway via your domain.
