michaelmurfy: 2nd post on the first thread you linked to - you need to specify the interface (ADSL, VDSL or Fibre) to forward the ports from. I've done it in the past and it has worked fine.
Also it has almost been a year since the Spark name change. Can we please stop referring Spark as Telecom? We all know who Spark is now so there is no need to even mention Telecom anymore. I also believe if you upgrade the firmware from their website here then you get the full blown Spark branding (and also fixes bugs).
Personally I think these routers are great and work well, they're not as broken as you say.
Spark even provide a port forwarding tutorial here so I honestly have no idea why you called up Huawei, Spark always have and always will support the routers they provide to their customers even right down to port forwarding if you get the right person but they've actually got extensive help guides on their website relating to the routers they've either once provided or provide now.
We did check - ADSL all the way. Firmware upgraded. There have been more than a few flaws in the firmware provided by Tcom nad other ISPs, especially their inability to save data from the front end to the back end of the system.
We use Draytek, microtik and a few other brands when we supply. all of them together have never caused as many problems as the TCom branded routers we have run into. Thier special setup routine breaks more thna it fixes and their routers are notoriously underwhelming.
Can anyone say Thompson?
I also got the Huawei port forwarding manual sent to me - highly deficient in detail and process. - It didn't work either.
The reason we went to Huawei is because the Telecom -- err spark support people forwarded our call there as they dont support those routers and that is Huaweis job. Trust me, i no more wnat to talk to router 'helpdesk' than I do spark help desks.
