I have much knowledge on the topic of Dial-in servers. I assume that you are setting up a shop that has older POS terminals that only allow network traffic via a modem. Well, you actually need two servers. I just had a bunch of information, and removed it because I can make this a lot shorter. I'll make a Microsoft Visio graph of what you need, and a Word document of how to do all of this. If you email me (at email@example.com
), I'll send the graph and Word document to you sometime tomorrow. I have set this up before, and it's very easy (depending on how much knowledge of networks you have).
