services requiring guaranteed Quality of Service (QoS). The Barricade
enables true telecommuting for the first time. It also provides
multiprotocol encapsulation for bridging Windows NetBEUI and Novell’s
IPX protocols directly to a remote site for complete access to corporate
resources, or for routing TCP/IP traffic for Internet connections.
Features and Benefits• High-speed Internet access over existing phone lines
• Full-rate DMT connection (8 Mbps downstream, 640 Kbps upstream)
and splitterless G.lite connection (1.5 Mbps downstream, 512 Kbps
upstream)
• Multiprotocol encapsulation of Windows NetBEUI, Novell’s IPX and
TCP/IP via bridging for complete access to corporate resources
• TCP/IP routing transport using RIP 2 for Internet access
• Network Address Translation (NAT) and Network Address and Port
Translation (NAPT) enables multiple user Internet access with a single
user account, flexible local IP address administration, and firewall
protection
• Virtual Server allows remote users access to various services at your
site using a constant IP address
• Dynamic Host Configuration Protocol (DHCP) for dynamic IP
address assignment as a server or server relay
• DHCP Relay enables a host to obtain basic TCP/IP configuration
information from a DHCP server, even if the server does not reside on
the local subnet
• IGMP Proxy capability allows users anywhere on a downstream
