Anyone that knows the IP address of your DERP node could add it to their DERP map and route their tailnet traffic through your DERP node. To allow only your tailnet traffic through your DERP node, run tailscaled on the same machine as your DERP node, and start derper with the --verify-clients flag:

sudo derper --hostname=your-hostname.com --verify-clients
