I have a number of services I’d like to host, and an old laptop with some of them set up and working on my network.
But I currently have a Google router, and the Google home app doesn’t seem to let you port forward. The “Port Management” option in Advanced Settings redirects to privacy settings.
There’s one port I forwarded before the app broke a few years ago, but I don’t suppose it’s viable to run multiple services through a single port.
Is there a workaround, or am I stuck until I can get a new router?
While you should probably fix your router, there are some workarounds that can work. If you have your own domain, cloudflare tunnels are really great. Similar option that doesn’t need a domain but requires a VPS or other hosting with a public IP is just a WireGuard tunnel to your service.
