I get the 3 processes: the call manager, the GRE gateway and the ppp1
process which is invoked. 

I get a successful connect message in /var/log/messages showing that the
correct IP addresses have been allocated and MPPE 128 bit compression is
being used.

It all looks fine.

BUT when I try to ping, traceroute or telnet to anything through the link
I'm unsuccessful.

The proxyarp stuff is working at the server end for 95/98/2000 clients so
I don't think that's the problem. I can tear down the link and connect
with 98 with the same username and password no problem.

One thing I did notice is that when I bring down this PPTP connection,
there is a very large number of bytes logged as transferred on the client
side - 10MB in a couple of minutes (this is obviously an error as the
modem cannot sustain that transfer rate.

I even tried rolling back to ppp-2.3.8 on the client to see if that would
help but it hasn't.

I'm on the verge of giving up on pptp for linux-linux VPN unless someone
can help me :(
