BT & Huawei working with us
We have also managed to confirm the issue on a BT Retail FTTC (fixed IP) line as well. It is very specific, and relates to PPPoE over an FTTC link, where recent IP/port combinations stop working after a PPPoE reconnect, but start if the Ethernet port is disconnected and reconnected.
We had several engineers at our offices working with us today, and engineers from BT at the exchange and Huawei in China on the phone as well. After several hours working with Paul we can confirm that they have managed to identify the problem and reproduce it in their labs.
Now we wait for a fix to be released and rolled out - no idea on timescales yet. We'll keep a close eye on it.
Once again, with all the ISPs and all the FTTCs lines in the country, it is A&A that are leading the way identifying issues like this and working with BT to resolve them. We are very pleased that it is actually taken seriously by both BT and Huawei.
Thanks to the customers who reported the issue and helped us pin it down, and well done to Paul in our offices for diligently identifying the issue and working with BT and Huawei to help them find the cause.
