PPTP not working - Again!

[BlueH2O]

This seems to happen at random times.. One day my PPTP connection is working, the next I can't connect. Today is one of the can't connect days. Here's a relevant chunk of log:

Oct 31 13:56:20 arturo pptpd[22595]: CTRL: Client xxx.xxx.xxx.xxx control connection started
Oct 31 13:56:20 arturo pptpd[22595]: CTRL: Starting call (launching pppd, opening GRE)

Oct 31 13:56:20 arturo pptpd[22595]: CTRL: Client xxx.xxx.xxx.xxx control connection finished

All the relevant ports and protocols are allowed through the firewall so I know that is not the problem.. This doesn't seem to be repeatable so It's got me baffled. A couple of times a re-install of pptp fixed it but today that is not working, and I'm pulling my hair out!!! :mad:

So a stop of the service, re-install, and restart service didn't help, but a reboot did. How very window$ like.. I'm thoroughly confused.

EDIT: nevermind, it's quit working again.. :mad:

Still working only some of the time in Fedora 9.. Anyone??
