[pptp-server] Protocol-Reject Issue

[Leonard L. Goldenstein]

Hello to everyone on the list.
I have seen this problem posted where pppd gives "Protocol-Reject for
unsupported protocol" messages to the system log.  Unfortunately I have not
seen much in the way of any solutions for the problem.  I ask that if anyone
has experience with this situation and/or a solution to please post to the
list to help out all others with this problem.

I have setup PoPToP 1.0.0 following a combination of the HOWTO on the
website and this document:
http://www.vanja.com/PPTP.txt

Software:
Linux 2.2.17
PoPToP 1.0.0 RPM
pppd-2.3.11.tar.gz
ppp-2.3.11-openssl-0.9.5-mppe.patch.gz

Everything compiled fine.

My options.pptp file is (yes, pptpd is set to use this file):
lock
+chap
auth
proxyarp
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless
ms-dns 1.1.1.4
ms-wins 1.1.1.4

I can connect to the server from Win98 with no problem:

etc...

However as you can see, after establishing the connection, i am unable to
send any traffic over the network.  All I get is the Protocol Reject
messages until I disconnect the connection.

*ANY* Help on this issue is *VERY* greatly appreciated.
Thank You.
