Hi Nick! There are two kinds of l2tp authentication mechanisms- host based and user based. Hist based auth for l2tp is not currently available in routerOS, but is the default for many (most) wholesale dsl providers. Could that be related to your problem? If so, there are only two ways that I know of how to solve it - one way is to convince the other end admins to use user based auth. The other way is to use a third party router (e.g Cisco) to terminate the l2tp tunnel and bridge it to a physical Ethernet interface. Hope it helps!

Was only a few changes away to get to that - but it still doesn't work or I have completely missed something. The remote-address in the secret should be what I want the DSL tail to get from the server, correct?
