[pptp-server] pptp still not working

[Kenneth E. Lussier]

After looking at your post, there could be several problems. The first
thing that I noticed is that in the Win98 Config you're specifying that
the client should use an IP address that is reserved in the pptpd.conf
as a local IP. Since you have pptpd set to assign IP addresses to
clients, set the client to obtain all info from the server and add your
dns server, wins server,etc., in the /etc/ppp/options file. 
As for the LCP timeout problem, that's usually caused when the client
can connect to the server, but the return traffic can't find it's way
back to the client. The server sends out the auth request and never gets
a response. Does the router know how to pass packets between the
subnets? Does the Linux box have routing enabled and set up to route
between all subnets correctly? Check out the link below for some
pointers on the config files.
