Pro: 1Gb upload and download speeds on free Internet provided by the HOA. Con: As a self hoster, I have zero control over it. No port forwarding, no DMZ, no bridge mode. It’s Starbucks free WiFi with a wired connection.
Option A: Buy Google Fiber and don’t use free Internet. Option B: Create some elaborate tunnel through a VPS.
My public self hosted activities are fairly low bandwidth (password manager, SSH). I have a vague idea that I could point my domain to a low cost VPS that has a VPN tunnel into my home network for any incoming connection needs. That may require me to fill in port forwards on both systems but whatever. Tailscale is serving most of my remote needs but I still need a few ports. This does not fix the issue of online gaming port forwards (Nintendo Switch online requires a huge forwarded range for best performance) but oh well for now.
UPDATE: I think they’re using this system. https://www.cambiumnetworks.com/markets/multi-family-living/ The personal Wi-Fi overview makes it clear each AP is given it’s own VLAN which sounds a whole lot like the whole building is sharing one IP and there’s no way I’m going to get my own Internet access. They even detail how you can roam the building and maintain your WiFi connection across your neighbor’s and the common areas APs. This is the IPV4 future.
I would do option A, but instead of just not using the free internet, I would use it for everything else not needing server services. So like streaming or general browsing.
Just leaving the Google fiber as a dedicated pipe for all my self hosted services
You can do this kind of split with pfSense easily
I just got a Ubiquti Dream Machine that can do fail over so the other connection won’t be completely wasted but $70 per month could be saved by finding another way.
