Product Brief

Nortel VPN Router 200 Series 

For small offices and home offices

Enterprises have been quick to see

the merits of the Internet and IP to

extend their business communications

to customers, employees and partners.

But the Internet was not designed

with security in mind. Nortel VPN

Router* products have led the market

in addressing these enterprise IP

security needs. Now the powerful

security of the VPN Router family

can be extended to small office and

home office sites. The VPN Router

200 series is an affordable all-in-one

solution for tying small satellite

offices and teleworkers into a secure

corporate network.

The VPN Router 200 series of VPN
devices (formerly known as Contivity)
are the answer to enterprises requiring
low-cost secure connectivity across the
Internet or managed IP networks.
Designed for telecommuter and small
office/home offices, the VPN Router
200 series provides Virtual Private
Networking (VPN), stateful firewall, IP
routing, URL/content filtering and
optional integrated DSL in a compact
easy-to-manage platform. 

Consisting of VPN Router 221 and 251
models, the VPN Router 200 series
provides options for small sites seeking
secure Internet connectivity along with
firewall-based perimeter defense func-

tions in a single device. Both models
have an integrated four-port Ethernet
switch for connecting local LAN devices.
The VPN Router 221 provides Ethernet-
to-Ethernet connectivity while the VPN
Router 251 offers integrated ADSL
conforming to international standards
to allow global deployment. 

Low-cost IP security 
for small sites 

With its low-cost and integrated services,
the VPN Router 200 is an affordable
device for small sites that might previ-
ously have felt such an IP security solu-
tion was too costly. It combines the
advanced IP-VPN, stateful firewall,
routing and content filtering functions
required by most telecommuter and
small office/home offices when connecting
to and accessing Internet services. It
further delivers these in a compact and
quiet chassis that neatly fits into these
environments.
