Good day, I really hope experts here can teach me how to setup a VPN because I'm neither a server administrator nor I'm good in networking. I wish to setup a VPN so that I can backup the files from my office to my computer at home. I understand that VPN is able to perform that. For your information, the network in my house is as below: Mode --> WiFi 4-Ports Router (also the DSL dialer) --> Computer 1 & Computer 2 Computer 1: Installed Windows 2003 Server. I've ran the Remote Access Wizard to setup a VPN, chose Typical Server Setup and clicked all the Next button for Microsoft to automatically setup everything for me (VPN, DCHP & DNS) I've also installed No-IP on my computer because I'm on a dynamic IP. Of course, when I tried to connect from my office, it gave me an error message, saying that it failed to connect to the VPN. Could my router be the culprit, since it has a built-in firewall? (The model is Netgear WGR614) If it is the culprit, what ports do I need to do the forwarding? I think the information that I've provided here is somehow limited, please let me know if you need anything else in detail. I will try my best to provide what I know. Thank you very much for your time reading this post and have a nice day!
