I've been seeing a similar problem with another router - which was caused by
broadcast storms exceeding allowable ADSL bandwidth...

Remember that even a 10MB connection is like 2x - 8x faster than an ADSL
downstream, and 17 - 20 x faster than a typical upstream. If the PPTP were
to generate "noise" it could max your bandwidth out, and the first thing to
disappear would be icmp packets - right?

Just a musing.
