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.

The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections.

There are two ways of assigning IP addresses to your network devices.

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers.

If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.

NAT (Network Address Translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet.

FTP: a standard protocol for sending files between computers over a TCP/IP network and the Internet

packet: a unit of data sent over a network

Static IP address: a fixed address assigned to a computer or device that is connected to a network.

ISP: a company that provides access to the Internet

Dynamic IP address: a temporary IP address assigned by a DHCP server.

DSL: an always-on broadband connection over traditional phone lines

DHCP (Dynamic Host Configuration Protocol): a protocol that lets one device on a local network, known as a DHCP server, assign temporary IP addresses to the other network devices, typically computers.

This failover capability is essential for businesses that rely heavily on internet connectivity.

The RV082 also boasts impressive VPN support, enabling secure communication between remote users and branch offices. With support for up to 50 simultaneous VPN connections, the router accommodates a growing workforce that may require access to the company’s network from remote locations. This is particularly beneficial for businesses with telecommuting employees or those that operate across multiple locations.

Security is a paramount concern for any business, and the RV082 addresses this with various built-in security features. It utilizes advanced firewall capabilities, including Stateful Packet Inspection (SPI) and Denial of Service (DoS) protection, safeguarding internal networks from external threats. The router also supports strong encryption protocols such as IPSec and PPTP, ensuring that sensitive data transmitted over the VPN remains secure.

Performance-wise, the RV082 includes eight switched LAN ports, allowing numerous devices to connect directly to the network without the need for additional hardware. This feature simplifies network management and helps keep connectivity organized. Furthermore, the router supports Quality of Service (QoS) prioritization, which allows businesses to allocate bandwidth effectively among different applications and users, promoting seamless performance even during high traffic periods.

The user-friendly web-based interface facilitates easy configuration and management, making it accessible for users with varying levels of technical expertise. Additionally, the RV082’s compact design ensures that it can fit into nearly any office environment without taking up too much space.

In summary, the Linksys RV082 is an excellent choice for businesses looking for a dependable and secure networking solution. With its dual WAN capabilities, extensive VPN support, robust security features, and user-friendly management tools, the RV082 successfully meets the challenging needs of modern business networking.
