802.11 a/g Wireless Networking

The WGU624 wireless router includes 802.11 a and 802.11g wireless access points, providing continuous, high-speed access between your wireless and Ethernet devices. The router provides:

• 802.11g and 802.11a wireless networking at up to 108 Mbps.

• 802.11g wireless networking, with the ability to operate in 802.11g-only, 802.11-turbo-g-only, or 802.11b+g modes, providing backwards compatibility with 802.11b devices or dedicating the wireless network to the higher bandwidth 802.11g devices.

• 802.11a wireless networking, with the ability to operate in 802.11a-only, 108 Mbps only, or Auto 108 Mbps modes.

• When Super G Modes is enabled, the wireless router will enable channel bonding, data compression, packet bursting and large frame support. Channel bonding takes two of the three usable channels in 2.4GHz 802.11b/g and uses them to double the speed.

• 64-, 128-, and 152-bit WEP encryption security.

• WEP keys can be generated manually or by passphrase.

• WPA and WPA-PSK wireless security.

• Wireless access can be restricted by MAC address.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the WGU624 is a true firewall, using stateful packet inspection to defend against hacker attacks. Its firewall features include:

• Denial of Service (DoS) protection. Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND

Attack, and IP Spoofing.

• Blocks unwanted traffic from the Internet to your LAN.

• Blocks access from your LAN to Internet locations or services that you specify as off-limits.

• Logs security incidents. The WGU624 will log security events such as blocked incoming traffic, port scans, attacks,

and administrator logins. You can configure the router to e-mail the log to you at specified intervals. You can also configure the router to send immediate alert messages to your e-mail address or e-mail pager whenever a significant event occurs.

• The WGU624 prevents objectionable content from reaching your PCs. The router allows you to control access to Internet content by screening for keywords within W eb addresses. You can configure the router to log and report attempts to access objectionable Internet sites.

Security

The WGU624 wireless router 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.

• DMZ Hardware Port A Demilitarized Zone (DMZ) is used by a company that wants to host its own Internet services without sacrificing unauthorized access to its private network.

The DMZ sits between the Internet and an internal network's line of defense, usually some combination of firewalls and bastion hosts. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers.

• 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 “DMZ” 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 WGU624 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 then configures itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto Uplink accommodates either type of cable to make the right connection.

technology. Each Ethernet port automatically senses

Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624

Extensive Protocol Support

The WGU624 wireless router 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 WGU624 wireless router 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 WGU624 wireless router 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.
