I try this, but not work

[adnane dakna]

are you using DSL connection ?

[Anton Pestov]

Optical fiber...

...when the very first time was connected everything worked with such configuration, and in half-day at night the channel was disconnected. From what it can occur?

[dinesh.thathanath]

Still relevant even today.

Your configs worked like a charm. Thanks.

[Anton Pestov]

Thanks to all for the help! ISP, at last, recognized an error on the side. On their side the binding to other MAC, distinct from from what PPPoE is initiated was registered.
