VPN through 9000SM

Hello,

I am trying to connect to my VPN at my CO through the SM which is running NAT. I am using PPTP encapsulation and MS-chap protocol. It gives me an error 619 The port is disconnected. How do I forward ports on this SM running version 6.1? Specs say that it does support VPN tunnels. Does it support PPTP? Please advise. Thank you.

Where the heck is motorola on these issues? :cry:

Just got off the phone w/ tech support. The SM only allows L2TP not PPTP.
