    &gt; Even in 2026, a huge number of ISPs still rely on PPPoE, including Bell Canada, AT&amp;T Fiber, and Xfinity in the US, along with the vast majority of ISPs in Europe, Asia, and China.<p>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).<p><a href="https:&#x2F;&#x2F;pon.wiki&#x2F;guides&#x2F;masquerade-as-the-bce-inc-giga-hub-2-with-the-was-110&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pon.wiki&#x2F;guides&#x2F;masquerade-as-the-bce-inc-giga-hub-2...</a>

      Sure, it bypasses the supplied hardware but does not solve PPPoE limitations on UniFi.<p>I use the same WAS-110 on Bell.

    I miss when this kind of content would&#x27;ve just been two paragraphs and a config snippet.<p>(also, this isn&#x27;t a &quot;Show HN&quot;)

    Oh thanks. My local ISP insists on pppoe even for business lines.<p>I like the unifi APs but then using their gateways is a no-no.

    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

        Could you go into more detail - how is the half-bridge less capable? (I&#x27;m not familiar with ether device, but the ultimate solution seems like a sub-optimal solution to me?)

          Essentially, it&#x27;s a case of smaller device with less powerful CPU and less powerful routing offloads, but which happens to have a hardware offload for the specific use case that they needed offloading - PPPoE.<p>As the article itself mentions, hardware PPPoE is often present on lower shelf chips, but missing from higher end chips that in turn have more switching&#x2F;routing capabilities.

    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 &#x2F;24? Is that reality in ISP last mile networks?!
      • hayleyest1 hour ago
        AT&amp;T offers only a &#x2F;25 here. But it&#x27;s just a shell script, adjust to whatever your flavor is. You can hardcode in your own netmask, bits, and gateway without any issue.

    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.
