I was jus trying to point out issues with MTUs and domain communication. If
this is not the cause, we need to look elsewhere.

That's interesting. I haven't heard of a routed ADSL connection and not
using PPPoE up until now.

Keep us informed. Maybe you can try some packet sniffing to see exactly
what's going on.
