locations. This carrier-class IP services platform stretches investment
dollars with low price/performance and total ownership costs and
delivers service-enhancing, revenue-building features.

Applications

• Advanced security services

• Site-to-site and remote access VPN services

• Bandwidth management services

• Mobile data services

• Shared Internet connectivity

• Secure intranets and extranets

Features

• Integrates firewall, VPN, QoS, VLAN, and virtual
firewall capabilities in one configuration

• 140 Mbps firewall performance; 3 Mbps 3 DES
performance; 55 simultaneous VPN tunnels; 4,094
VLANs; 20 virtual firewalls

• Intrinsically secure, transparent Layer-2 bridge

• Central staging and secure remote management via
Lucent Security Management Server (LSMS) software;
manages thousands of VPN Firewall Brick®units and
Lucent IPSec Client users from one console
