ATT Fiber vs Spectrum (alien.top)

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!

In Alabama. Don’t have CGNAT. The gateway does ip Passthrough fine, the newer BGW320 505 anyway. If you do ip Passthrough to your own router there won’t be any ports that will be blocked.

While rare, sometimes att will remotely update it and you may need to reconfigure ip Passthrough again. If you choose not to use ip Passthrough, port forwarding works fine it’s just awkwardly implemented.

I thought I would hate att but the service has been way more stellar than I thought. However the customer service is god awful, too many policies road block quality service.

In my setup I often get more bandwidth than I pay for. So much so I downgraded to 300/300 and usually see 400ish+ sometimes.
