I appreciate it is usually PPPoA, the question is can you use PPPoE. I'm doing this via PPPoE with a Speedtouch 510 in bridged mode.
To connect an ethernet router WAN to UK ADSL you'll need either a router with a bridge mode or some fudge to pass over the external IP. There's a Vigor 120, ADSLnation X-modem and a few others around. Most rely on PPPoE on the ethernet router for the login, hence the question.
MaxDSL - goes as fast as it can and doesn't read the line checker first.
