I have looked at the user's guide on the pipeline and it sound like I need two units to establish a VPN, is this correct? What I am trying to do is setup a dial-up ISDN with the pipeline so that our people can access the interenet. Then I want to be able to connect from home over the internet to the ISDN connection (I have a cable modem at home) to be able to download and upload files. I was told I could do this, but I would have to configure the pipeline to autodial. It would seem to me that unless the ISDN line was up all the time, this would not work. Any IDEAS!!!!
