[pptp-server] win2k, pptpd 1.2.2, pppd 2.4.0 and Linux 2.4.2

[Keith T. Garner]

I just setup and got running pptpd 1.2.2 on a
machine with the 2.4.2 kernel.  I followed the HOWTO at
http://home.swbell.net/berzerke/2.4_Kernel_PPTPD-HOWTO.txt.  It was a
great amount of help, thanks to whomever threw it together.

After digging through the past two months worth of archives on this
mailing list, it looks like I've hit what has become a common problem.

Using win2k with encryption off, it works flawlessly.  Packets go back
and forth with easy, giving me access to our private networks.

However, using win2k as a client against the server with encryption on
(128 bit stateless) all packages between ppp0 on the server and the
win2k client seem to just disappear into the void.  As others have said,
packets appears to be going over the line thanks to the blinky lights
on win2k, and I do see "ACCEPTS" being matched in the iptables.

I just wanted to toss out that "yes, this is a real problem, and it
appears to be an issue with mppe and win2k."  I haven't had a chance
to test it with other clients yet, and I plan on doing it either this
weekend or on Monday.

Actually, my coworker had a win98 box up that I could test with quickly.
Doing both encyrpted and non-encrypted connections, the win98 box can
connect and work flawlessly as a pptp client.

So, to sum up, win98 works well both encrypted and nonencrypted.
win2k only works well unecrypted.  Adding more logs to the fire of
"win2k isn't working encypted with the stone soup in the subject."

Anything I can do to help, send logs to the list or whatever, let me know.
(I'm too mentally fried this week to dig into it further at this point.)
