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

Security

The FWG114P Wireless Firewall/Print Server is equipped with several features designed to
maintain security, as described in this section.
• PCs Hidden by NAT: NAT opens a temporary path to the Internet for requests originating from
the local network. Requests originating from outside the LAN are discarded, preventing users
outside the LAN from finding and directly accessing the PCs on the LAN.
• Port Forwarding with NAT: Although NAT prevents Internet locations from directly accessing
the PCs on the LAN, the router allows you to direct incoming traffic to specific PCs based on
the service port number of the incoming request, or to one designated "DNS" host computer.
You can specify forwarding of single ports or ranges of ports.

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
PC 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, Firewall, and
• IP Address Sharing by NAT: The FWG114P Wireless Firewall/Print Server 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.
