Have you followed the instructions at http://www.shorewall.net/PPTP.htm for 
setting up a PPTP server on your firewall?

If so, is the XP system that you are trying to connect from in your local 
network or is it an external system?

Re: pptp / shorewall problem (Error writing GRE packet: Operation not permitted)

Hi...


check if you have compile the module ppp_mppe or the ppp_generic have
patch install to support mppe.

The ppp daemon have to configure and install with support MPPE.
