  16. Configuring Dial-on-Demand Routing • Demand-dial routing • Allows a server to initiate a connection only when it receives data traffic bound for a remote network • Can use dial-up networks instead of more expensive leased lines MCTS Guide to Microsoft Windows Server 2008 Network Infrastructure Configuration

  17. Configuring Remote Access Services in Windows Server 2008 • Dial-up networking • Connects remote users to their networks using a standard phone line • Virtual Private Networks • Allow client connections to your network from remote locations • Works by creating a secure tunnel for transmitting data packets between two points • VPN tunneling protocols: Point-to-Point Tunneling Protocol, Layer 2 Tunneling Protocol, Secure Socket Tunneling Protocol MCTS Guide to Microsoft Windows Server 2008 Network Infrastructure Configuration

  18. MCTS Guide to Microsoft Windows Server 2008 Network Infrastructure Configuration
