[pptp-server] DTE problems with PoPToP ?

[John Sutton]

Hi Paulo

This looks like the same problem that I've been having for about 2 months
;-(  I've given up for the moment and am content with watching this list to
see if anything turns up.

My scenario is:  PPTP over local LAN works, over dialup connection fails.
I was also sitting behind a firewall so I eliminated this but it made no
difference.  I also had intermittent results, I think on one occasion it
did work (but it's all a bit hazy now ;-).

I used the linux pptp client to try to get a handle on the problem and
found that the LCP requests sent by the server are received and replied to,
but these replies never get back to the server.  Perhaps you could try with
the linux client and see if you get the same result?

I never tried messing with the DTE speed (seems *too* wacky to be relevant)
but I'll have a go at this when I get the chance.
