I have found a few how to's on PPTP and Debian although is it necessary to install kernel-patch-mppe package?
as mentioned in http://www.chiark.greenend.org.uk/~owend/free/pptp-debian.html


Here is another how to I found http://pptpclient.sourceforge.net/howto-debian.phtml#kernel
and it is mentioned if not connecting to a MS VPN server than the MPPE patch should not be required the VPN I am connecting to is from a linux box to a Cisco PIX firewall.  after I followed the instructions I got errors about ppp not being enbaled in the kernel, if I do enable it in the kernel than what parts of PPP need to be enabled in the kernel there are several.  

Does anyone else have any good information on connecting from a linux box to a PIX firewall for a VPN connection.  I am not sure what needs to be done.
