Introducing the Nortel Business Secure Router 252
The Business Secure Router is an ideal secure gateway for all data passing
between the Internet and the Local Area Network (LAN).
Your Business Secure Router integrates high-speed 10/100 Megabits per second
(Mb/s) autonegotiating LAN interfaces and a high-speed Asymmetrical Digital
Subscriber Line Plus (ADSL2+) port into a single package. The Business Secure
Router is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks. By integrating Digital Subscriber Line (DSL)
and Network Address Translation (NAT), the Business Secure Router provides
easy installation and Internet access. By integrating firewall and Virtual Private
Network (VPN) capabilities, the Business Secure Router is a complete security
solution that protects your Intranet and efficiently manages data traffic on your
network.
Using the embedded WebGUI, you can easily set up and manage the Business
Secure Router using an Internet browser.
