Reference Manual for the Model FWAG114 Cable/DSL Wireless ProSafe Firewall
1-4 Introduction
Extensive Protocol Support
The FWAG114 wireless firewall supports the Transmission Control Protocol/Internet Protocol
(TCP/IP) and Routing Information Protocol
(RIP). For further information about TCP/IP, refer to
Appendix B, “Network, Routing, Firewall, and Basics.”
IP Address Sharing by NAT
The FWAG114 wireless firewall allows several networked PCs to share an Internet account
using only a single IP address, which may be statically or dynamically assigned by your
Internet service provider
(ISP). This technique, known as NAT, allows the use of an
inexpensive single-user ISP account.
Automatic Configuration of Attached PCs by DHCP
The FWAG114 wireless firewall dynamically assigns network configuration information,
including IP, gateway, and domain name server
(DNS) addresses, to attached PCs on the LAN
using the Dynamic Host Configuration Protocol
(DHCP). This feature greatly simplifies
configuration of PCs on your local network.
DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the router provides its own
address as a DNS server to the attached PCs. The router obtains actual DNS addresses from
the ISP during connection setup and forwards DNS requests from the LAN.
PPP over Ethernet
(PPPoE)
PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by
simulating a dial-up connection. This feature eliminates the need to run a login program such
as Entersys or WinPOET on your PC.
Easy Installation and Management
You can install, configure, and operate the Model FWAG114 Cable/DSL Wireless ProSafe
Firewall within minutes after connecting it to the network. The following features simplify
installation and management tasks:
Browser-based management
Browser-based configuration allows you to easily configure your router from almost any type
of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is
provided and online help documentation is built into the browser-based Web Management
Interface.
Smart Wizard
The FWAG114 wireless firewall automatically senses the type of Internet connection, asking
you only for the information required for your type of ISP account.
