There are disadvantages and advantages to both hardware and software routing platforms. Employees must be able to understand the benefits of both and able to translate that knowledge to our customers.
SECTION A: WRT54G SOHO Router
The Linksys WRT54G router is a 2.4 GHz Wireless-G (802.11g) SOHO (small office/home office) device. This device provides about a 100 meter range for both wired and wireless devices. The function of the WRT54G is to allow locally connected computer internet access. The router provides NAT (Network Address Translation), Firewall, Proxy and Encryption services. Linksys manufactures the router and are a Division of Cisco Systems, Inc. (Linksys, 2005). NAT provides a means for multiple computers to connect to the internet using one connection or route. Firewall/Proxy application provides packet filtering to secure the network by controlling which packets are allowed to ingress and egress the device. The job of the default gateway is to direct traffic towards the ISP so that those packets can then be routed to the internet. This guide will serve as a means to providing basic configuration for the WRT54G router by no means is this guide considered a comprehensive configuration guide for the router.
Get to know the Router
This Procedure Guide has been developed to explain how to configure a LINKSYS WRT54G wireless router. The WRT54 is a Dual-Band router capable of supporting IEEE 802.11 Wireless standards B,A and G. WRT54G Broadband Router is like four devices in one box! The Router function lets you securely share one high-speed Internet connection among your entire network, while the 4-port full duplex 10/100 Switch jump-starts your wired-Ethernet network. The first Access Point uses the 2.4GHz radio band, supporting both the popular and inexpensive Wireless-B (802.11b) standard at 11Mbps, and the almost five times faster, Wireless-G (802.11g) at 54Mbps. The second Access Point radio operates in the 5GHz band, and supports Wireless-A (802.11a) networking at 54Mbps. Since the two radios operate in different bands, they can work simultaneously, blanketing your wireless zone with bandwidth. (WRT54G-v5, 2005).
SECTION B: Configure Network Address Translation
Network Address Translations has a very important role it plays when connecting information systems to the internet. NAT has the capability to translate multiple Internet Protocol (IP) addresses on the users private Local Area Network (LAN) to one public IP address that is normally provided by the Internet Service Provider (ISP). NAT adds a level of security by providing a defense in depth solution in that a threat agent would only see the information provided on the public facing interface and have no known knowledge of the internal networking scheme because user internal IP addresses are never transmitted beyond the LAN boundary. Because of the rapid expansion of the internet and scarcity of IP address Network Address Translation (NAT) was...
