Beginner ?: Secure networking online

Please be patient - at best we are just novices!!!

We would like to learn how to network two offices in two different states sharing the same information - security is a must of course. I have heard about static ip's, pc anywhere, etc. and as a result am a bit confused. We are/will be using Windows XP (with the latest updates) and dsl connection. Where do we start? What do we need to know to make an educated decision? What should we use or avoid?

 

What you need is a WAN connection.

PCAnywhere is mainly for teleworking, not good for networking two LANs together. Static IPs would help, but isnt totally nececary.

You need a Point to Point connection, having a server in one location to store information on. I would make a VPN connection from one server to another, which would then link the two networks.

I think you might be best of getting a consultancy company in to sort out somthing for you. Overall it would be more efficient for you.

 

What you are looking for is called VPN.

What's a VPN? - Virtual Private Networks

Quote from: http://vpn.shmoo.com/

These are secured private network connections, built on top of publicly-accessible infrastructure, such as the Internet or the public telephone network. VPNs typically employ some combination of encryption, digital certificates, strong user authentication and access control to provide security to the traffic they carry. They usually provide connectivity to many machines behind a gateway or firewall.

===================================================

VPN is based on very strong encryption and certificate. It needs a lot of power to perform well.
So if you are looking for a permanent working solution you might consider VPN Appliances.

In order to establish VPN you need a VPN server on one side (Aka VPN End Point) and a VPN client on the other. Example: Linksys: WRV54G - Wireless-G VPN Broadband Router.

If both done in software the connection will work very Slowwww. Most businesses have a VPN appliance that executes the VPN server side in its own hardware. Doing so enable employees to connect to work using VPN fast.

Most Cable/DSL Routers are VPN through I.e. the Router allows the VPN to pass through but does not actually participate in the process. If VPN is really important you should consider buying a Router that is actually a VPN end. I.e. your Router is also a VPN server.

If the connection and the sharing are more casual and mainly done for File transfer, there is a way to avoid VPN all together by using an encrypted remote control program.

Example: Ultr@VNC (Remote Control over the Internet & Network) - Installation, and Settings.
