I have seen some posts on this board about problems with using the safe@office 500 ADSL with static IP addresses on BT ADSL lines. These all date back to 2006 and I was wondering if the issues with the way BT implement these static addreses have been resolved yet. BT send a dynamic address that is not in the static range as a "carrier address" and we cannot seem to configure the static addresses on PPPoA.

please make sure you are using ipoa either fixed ip or dynamically received this is supported from 7.5.x make sure you have the latest one
