I need help to configure PPTP on my network. Right-now there is a new Cisco WAG320n modem connected. Before that there was a old low grade router which never caused the configuration issue. I am going for a new setup where I am facing a connectivity failure issue. The technician game me list of entire process for configuring pptp. But still I am stucked at some place. I need help to find right settings for both Windows and Linux.
