See I do put the blame on BT, well at least partially. These things should be tested and tested in every production environment before rolling out to the business (i.e, us). If glaring problems were found, then source an alternative rather than us being in the situation we are now. As such, we have a convoluted problem and partial workaround which may or may not work depending on the day we try, seemingly at random. Throw in the fact that it's acknowledged the Firewall won't work is a bit of a joke quite frankly.
