Autosensing Ethernet Connections With Auto Uplink; Extensive Protocol Support - NETGEAR FWG114P Reference Manual

Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P

Autosensing Ethernet Connections with Auto Uplink

With its internal 8-port 10/100 switch, the FWG114P can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are
autosensing and capable of full-duplex or half-duplex operation.
The router incorporates Auto Uplink
whether the Ethernet cable plugged into the port should have a 'normal' connection such as to a
computer or an 'uplink' connection such as to a switch or hub. That port will then configure itself
to the correct configuration. This feature also eliminates the need to worry about crossover cables,
as Auto Uplink will accommodate either type of cable to make the right connection.

Extensive Protocol Support

The FWG114P Wireless Firewall/Print Server 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, and Firewall
• The Ability to Enable or Disable IP Address Sharing by NAT. The FWG114P 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. This feature can also
be turned off completely for using the FWG114P in settings where you want to manage the IP
address scheme of your organization.
• Automatic Configuration of Attached PCs by DHCP: The FWG114P Wireless Firewall/Print
Server 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 computer.
• PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.
