An update!
Well, the heating controller engineer attended and despite what I had read about BT's Hub, found a menu which enabled the router to be pinged. In fact I have just pinged it from home. So please accept my apologies MHC for my doubts.
The router is described as a BT BHub6-C7M8 Note that this is on ADSL, not FTTC
The controller is a Siemens. He opened up the Router's Firewall and from home I can access the Siemens log-in screen via the above Router. Problem is keying in the same username and password which I use when using a PC connected to the BT BHub6 where all works well and I get a msg that the User Name and/or Password are incorrect.
The controller eng left scratching his head.
So thinking whether there is something that the BHub6 does not like etc, it may be worth trying another router. ISTR reading that with BT BB you don't need a username/password as you do with other ISPs, do I leave those fields blank or do I need to input something else?
Also any ideas re the Firewall? Could it be as simple as it wanting to know the IP address of authorised users (such as myself) in advance?
Many thanks.
Cheers!
