How to Use Skype on LAN Only

Skype needs to connect to the Internet to verify account information, and generate encryption keys. The Skype network is created by all of its users; it's a peer-to-peer network. Every computer connected acts as a client and a server. Once a Skype account authenticates online it can operate within your LAN. Since Skype uses the fastest connections available to it, it will remain within your LAN as long as all the users it's communicating with are within that LAN.
