10/100 16-Port VPN Router Chapter 2: Networking Basics An Introduction to LANs A Router is a network device that connects two networks together. The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these two networks.
10/100 16-Port VPN Router A DHCP server can either be a designated PC on the network or another network device, such as the Router. By default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP). The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.
10/100 16-Port VPN Router A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user. 2. Data Sniffing Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks, such as the Internet.
10/100 16-Port VPN Router • VPN Router to VPN Router • Computer (using VPN client software that supports IPSec) to VPN Router The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software that supports IPSec can be one of the two endpoints. Any computer with the built-in IPSec Security Manager (Microsoft 2000 and XP) allows the VPN Router to create a VPN tunnel using IPSec).
