Do we know for certain that this is in pptp and not the overlying ppp? For
example, is the problem observed running the same ppp config to the same
server over a modem link?

Alternatively, is there some way of testing the GRE component
independently of the ppp?

IIRC there was a GRE-traceroute kicking around somewhere - could that be
hacked to some advantage here?
