Wireless-G ADSL Home Gateway Chapter 2: Planning Your Network The Gateway’s Functions A Gateway is a network device that connects two networks together. In this instance, the Gateway connects your Local Area Network (LAN), or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks. The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers.
Wireless-G ADSL Home Gateway Since you use the Gateway to share your 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 Gateway. You can get that information from your ISP. Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.
Wireless-G ADSL Home Gateway telecommuters, and/or professionals on the road (travelers can connect to a VPN Gateway using any computer with VPN client software that supports IPSec, such as SSH Sentinel.) There are two basic ways to create a VPN connection: • VPN Gateway to VPN Gateway • Computer (using VPN client software that supports IPSec) to VPN Gateway The VPN Gateway creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure.
Wireless-G ADSL Home Gateway e-mails are sent to their destination, or when you have to connect to your company's network when you are out on the road? How is your data protected? That is when a VPN can help. VPNs secure data moving outside of your network as if it were still within that network. When data is sent out across the Internet from your computer, it is always open to attacks.

Wireless-G ADSL Home Gateway What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a computer connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Gateway to be used with low cost Internet accounts when only one TCP/IP address is provided by the ISP.
Wireless-G ADSL Home Gateway The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do? Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.
Wireless-G ADSL Home Gateway Is the Gateway cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the Gateway. How many ports can be simultaneously forwarded? Theoretically, the Gateway can establish 520 sessions at the same time, but you can only forward 10 ranges of ports. What are the advanced features of the Gateway? The Gateway’s advanced features include Advanced Wireless settings, Filters, Port Forwarding, Routing, and DDNS.
