A little background:
We have three BT FTTP connections, made via third party Omada routers. These were all working fine up until Monday this week, when all three connections went down. On investigation all three were found to be authenticating and connecting but receiving an external IP address in the private 10.0.0.0/8 range. A call to BT revealed that all three connections had been blocked and we were told to wait 4-7 hours for them to be unblocked. Two of them went live within 30 minutes but the third remains down four days later. This is still presenting the same symptoms.
I have tried an alternative Netgear router, which produces the same result. However a BT Hub will connect. Am I correct that the Hub does not present credentials when making a connection? If so, how does it authenticate itself? I have drawn a blank with BT support; they cannot explain why I am assigned a private IP when connecting with the supplied credentials (they confirmed them to be correct), couldn't see that the connection had been blocked and didn't seem to think that it was a problem as long as the BT Hub was working.
Can anyone shed any light on this issue? I am not sure what questions I need to be asking. Can I request the connection to be rebuilt/reset?
Any help would be greatly appreciated.
Thanks in advance,
Faqinel.
