Multiple PPPoE on Single nbn Line - Anyone Tried It?

Lgzy2001 on 13/03/2024 - 15:09

Hey folks,

I'm thinking of trying multi-dial (aggregating bandwidth with multiple PPPoE sessions) on my single NBN line. My setup's pretty straightforward: FTTP connection goes into a switch, then into a router that's set up with multiple WANs.

With my current setup at mate NBN, I get the typical evening speed of 97Mbps download and 17Mbps upload on the 100/20 plan. After trying out multi-dialing, I noticed my download speed bumped up to 108Mbps, while my upload speed didn’t change at all (which is expected). In theory, I'd expect download speed to double (97*2) with multi-dialing, but I guess there's a chance that the ISP or nbn might shape the bandwidth.

Anyone else given this a shot? Specifically, does anyone know if any other ISPs are cool with this setup?

Cheers!

    Why not just change to mate 250/25 plan

    EDIT: I see, you want to "multi-dial" the same connection twice so only pay 100/20 to get 200/20. My initial thought was you are paying for 2 x 100/20 plans.

    thats one way to break TOS and get your account canceled

      Where does it say you can't do that?

        probably falls under exploitative use:
        (v) any other use of a Service in a manner that cannot reasonably be
        considered to be within the range of uses for which the Service are
        ordinarily supplied – provided that use of a Service is not Exploitative Use
        merely because it is high volume use.

          That is arguable…

    May i elaborate how you set up multi dial?

      Edit: assuming FTTP, you may or may not need a network switch.

      UNI-D -> Switch Port 1
      Switch Port 2 -> Router WAN1
      Switch Port 3 -> Router WAN2
      Switch Port 4 -> Router WAN3
      …

    This is also referred to channel bonding yeah? I think this increases latency though.

    • gzy2001 on 13/03/2024 - 20:56

      Channel bonding is a Wi-Fi thing, I think 'load balancing' should be the right term.

    I think the NBN have rate limit set up on the network. I recall I read some document saying if your actual speed is approaching the purchased one NBN will drop your packet within their infrastructure (not from your RSP). I could be wrong because I know for many other countries, Multi-WAN PPPoE is doable because the speed limit is applied not on the line but at the account level (on ISP RADIUS).

    • Chaddy on 17/03/2024 - 19:31

      Yes they NBNCo do have rate limits setup on the network and they do block ports for over use.
      You can get bonded connections on business plans but honestly if your on FTTP just order a 1000Mbps plan and be done with it. Or order 10GBPS from TPG or Telstra if you have an ABN and if the service is available. Plenty of partners can offer those plans as well. You could download the entire internet with that plan just about.

        Just to add to this a bonded connection is where an ISP will order two different NBN connections and join them together hence improving the speed but its not really common on NBN, it was more common back in the ADSL 2 days.

    Thats a lot of P’s

    The rate limit is provisioned on the user port on NTD by different plan tiers. That's why you see almost exactly the same speed tiers across all NBN retailers.

    Some retailers still use PPPoE so you can do multi-dial for slightly higher speed. You're essentially just getting your connection's overheads back. My guess is that you're still rate-limited between NTD and POI, but gain a bit more speed from POI and onwards. While you'll likely unable to do anything about it if you're on IPoE (the one doesn't need dialing).

    Multi-dial on PPPoE was quite common among powerusers in China to double, triple or even quadruple their speed, because the ISP also build their infrastructure (instead of sharing a common last-mile service provider like NBN) so rate limit is done at BRAS which also provides PPPoE auditing, and also when internet plans are way slower than the hard-limit posed by GPON.

    And of course, such method will likely break the service agreements.

      I wonder if this would be any different for network through Opticomm/LBN.

      Interestingly dodo also created their own tier of 15/5, which I guess is based on nbn's 25/5 and this speed is therefore feasible?

      • xmagic on 27/03/2024 - 13:22

        Or it’s just a upsell of 12/1 tier and hope consumers don’t find out? Could be. Just doesn’t make sense economically unless they’re charging way more than the MRP.
