> Even in 2026, a huge number of ISPs still rely on PPPoE, including Bell Canada, AT&T Fiber, and Xfinity in the US, along with the vast majority of ISPs in Europe, Asia, and China.

Comcast (Xfinity) does not use PPPoE.

In my specific situation I was able to use this WAS-110 to get full speed PPPoE from my fiber provider (Bell).

Sure, it bypasses the supplied hardware but does not solve PPPoE limitations on UniFi.

I use the same WAS-110 on Bell.

The UCG Fiber numbers make the case: this is a SoC acceleration gap, not a PPPoE overhead problem. Half-bridge is a workaround for hardware Ubiquiti shipped.

Oh thanks. My local ISP insists on pppoe even for business lines.

I like the unifi APs but then using their gateways is a no-no.

I miss when this kind of content would've just been two paragraphs and a config snippet.

(also, this isn't a "Show HN")

I always suspected this was possible but having it demonstrated is excellent. I would assume this would be of most benefit on an OpenWRT box which _does_ support hardware offload!

I mean at this point just ditch the Unifi? You have a much more capable gateway in play now that needs to have equal to greater throughput than the one you are bridging for.

No, the half-bridge is less capable for various functions, but happens to have hardware PPPoE offload which makes it faster for this specific function but not for others

I guess what they did works but it makes some of valid ip addresses unavailable.

Was thinking along the same lines; why do we hardcode a /24? Is that reality in ISP last mile networks?!

Comment by hayleyest 9 minutes ago

AT&T offers only a /25 here. But it's just a shell script, adjust to whatever your flavor is. You can hardcode in your own netmask, bits, and gateway without any issue.
