[pptp-server] pptpd problems getting connected

[Nick Rout]

I am having problems with pptpd on a linux firewall box. I am pretty sure I 
have dealt with gre and port 1723 correctly. here is a log. on the windows 
98 end I get an error 650. after the attempt pppd is left running 
(according to ps) and needs to be killed. It has a pid one higher than the 
pid for pptpd shown in the logs.

I have had pptpd going previously and my options are all the same as on the 
other machine it ran on. can anyone give me any pointers please?
