I have been able to connect both my mac mini and ipad to the PPTP server using the device options, settings in the OS but when I try to connect a router as a gateway to the PPTP server it never connects. I have exhausted my knowledge base and I'm looking for some help. The router is a Cisco Valet M20 and I have tried the OEM firmware and the DD-WRT but i have the same result no connection to the server.
