Part 1: Product description
The IBM High Rate Wireless LAN Gateway provides small offices and home
offices (SOHO) an economical way to connect a small local area network
(LAN) to the Internet using an external DSL/Cable modem. With its built-in
wireless access point, you can connect your IEEE 802.11b-compliant mobile
computers or other clients to establish a home network.
The IBM High Rate Wireless LAN Gateway has the following features.
v High-speed Internet access: Connect an external DSL/Cable modem to
provide Internet access 10-100 times faster than a 56k modem.
v Wireless access point: The IBM High Rate Wireless LAN Gateway contains
an embedded wireless access point that supports the industry standard
(IEEE 802.11b WLAN) protocol with a data rate up to 11 megabits per
second (Mbps), can have up to 63 simultaneous users, and is compatible
with all WiFi IEEE 802.11b-compliant wireless LAN (WLAN) client cards
with seamless roaming between access points.
v Built-in switch: With a built-in four-port, dual speed (10/100 Mbps)
Ethernet switch, you get complete and fast connectivity for small offices.
v Single shared ISP account with network address translation (NAT):NAT
works by translating the data packets’ IP address from the one provided by
the Internet service provider (ISP) to the IP address of the computer
connected to the IBM High Rate Wireless LAN Gateway. All computers on
the network can share a single ISP account.
v Dynamic host configuration protocol (DHCP): The IBM High Rate Wireless
LAN Gateway provides IP address acquisition and management.
v Web-based management: The IBM High Rate Wireless LAN Gateway
simplifies management with a built-in, Web-based setup utility.
v Built-in firewall: The IBM High Rate Wireless LAN Gateway has a built-in
firewall to protect the computers on the local network from hackers on the
Internet.
– NAT: NAT hides the IP address of the local network from the Internet.
– Packet filtering: Data packets without a trusted IP address or port are
dropped. For DMZ, the exposed computer receives all packets that would
otherwise be dropped.
– Stateful inspection: Data packets are inspected for relevance within a data
stream or session. If the data packets are not relevant to the session that
contains them, they are dropped. For DMZ, the exposed computer
receives all packets that would otherwise be dropped.
v Virtual Server: With the IBM High Rate Wireless LAN Gateway, you can set
up a server on your local network that can be remotely accessed from the
Internet (an ftp server, for example).
