That's right! :-) Cisco supports two modes of l2tp tunnel auth: 'host based' (I believe this is either the default mode, else considered 'industry standard' by many) and 'user based' which is the only method supported by routerOS. I have had some discussion with MT team about this, seeking implementation of 'host based' authentication mode with routerOS, but (although they did not say it precisely) my understanding of the situation is that it is a cisco proprietary mode and would require some modification of core linux kernel code which is unlikely to happen any time soon. Therefore, the only two options are as per my previous comment on this topic: either convince the other end to use user-based auth, or use a 'cheap' cisco router to terminate the tunnel and bridge it to an Ethernet segment ;) Cheers!

Interesting Tim, I always thought there was some incompatibility which stopped you from using a MT box as an LNS with a Cisco LAC, happy to be proven wrong as I would love to see this working as it would be a very cost effective LNS especially as I am about to upgrade my Cisco LNS.....
Regards Paul

Hi Nick,
That's not quite how it works on MikroTik.
Remove l2tp-server interface binding.
Then click L2TP-Server button in PPP.
Check the box [X] Enabled Then set your default profile. Then disable MSCHAPX.
That should sort your problem.

Thanks Tim,
There is a VLAN and a /30 between myself & the provider, BGP established over that link and they send all traffic form their loopback IP over to my side of the /30.
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?
This is what I have so far if it helps
