•
High-speed Parallel Port Connection
36 pin Centronics, bi-directional IEEE 1284 compliant (supports Nibble mode) with up to
1.5Mbps transfer rate
Content Filtering
With its content filtering feature, the NETGEAR ProSafe Firewall prevents objectionable content
from reaching your PCs. The firewall allows you to control access to Internet content by screening
for keywords within Web addresses. You can configure the firewall to log and report attempts to
access objectional Internet sites.
Configurable Ethernet Connection
With its internal 4-port 10/100 switch, the NETGEAR ProSafe Firewall can connect to either a 10
Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN interface is
autosensing and is capable of full-duplex or half-duplex operation. An uplink switch is provided
for cascading to an external Ethernet hub or switch.
Protocol Support
The NETGEAR ProSafe 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, “Networks, Routing, and Firewall
Basics

•
IP Address Sharing by NAT
The NETGEAR ProSafe 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 Network Address Translation
(NAT), allows the use of an inexpensive single-user ISP account.
•
Automatic Configuration of Attached PCs by DHCP
The NETGEAR ProSafe 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.
