[pptp-server] !!PLEASE HELP!! Emergency

you gonna get problems there mate!
i have two quick checkup points:

1 use only one IP address for local ip.
2. 'localip' and 'remoteip' should be of the same subnet. e.g., if you want the
remote ip address to be like 192.168.1.235-239, put something like 192.168.1.x
in the local ip.
and this should work.

cheers
