I am quite novice at networking so please excuse my niavity. I work for a company who has a LAN which consists of about 20 machines connected to a server. My company has another office at the other end of the country which has a small peer to peer network consisting of three pcs which share an internet connection via an broadband router. I was wondering what I would need to do and what equiptment I would need to have to allow the small peer to peer to be able to be connected to my server. In other words I wish to build a WAN. Any advice and information would be greatly appreciated.

VPN routers.

Netgear has an inexpensive, good model:

You would allow the routers to create a VPN there by joining the two networks together.

You must also have some sort of broadband access (duh), and remember that outbound speeds on Cable/DSL are usually the bottleneck. So that 30 meg file that is copied on the LAN in moments, will take a bit longer across the WAN.

or a vpa (virtual private network) Using remote access. depending on your operating system, windows 2000 supports this
