Hi all, just getting into home labbing the past few months. I have a small cluster of Proxmox machines running many of the usual services.

Currently running a 350x10 Spectrum cable internet connection. This is working just fine and has been shockingly stable for five years. It also keeps a very sticky public IPv4 address that has been perfect for self hosting and a cloudflare tunnel. It’s a modem only that goes into an OPNsense VM.

Upload is obviously a bottleneck that has become frustrating. AT&T Fiber came through the neighborhood a few months ago and are offering a 300x300 FTTH with no installation, fees, caps, contracts etc for less than the Spectrum connection. I’d love to jump on it but have read in a few places that they sometimes use CGNAT, the gateways don’t behave well in passthrough mode, mess with traffic, block ports, etc.

I guess the question is then, what are people’s experience with ATT fiber and homelabbing? Is there anyone who won’t lie about it that I could call before install? In SC if it matters. Thanks!

    I tried AT&T fiber for a month, but it’s a never-ending arms race between their absolute piece of shit gateway and the new methods people develop to bypass it. In the end I went back to the awful 15mbps upload of cable I could use with my own equipment, over the symmetrical gigabit fiber with a mandatory gateway (with a rental fee) which I’d only use in “passthrough mode” that still runs every packet through a state table that maxes out at 8000 entries. I was paying rent for a device whose only purpose was to authenticate to their network and throttle my traffic.

    Still bitter about it, clearly lol. I’d pay 4x as much if I could just get an ONT.

    If you don’t mind the state table and rental fee things, you’ll probably be fine. Just be sure to run everything behind the gateway behind your own firewall, since AT&T can log into it and change whatever they want any time.
