Chapter 5 Internet access

NN47922-501

Basic setup complete

Well done! You have successfully connected, installed and set up your Business 
Secure Router

 

to operate on your network, as well as access the Internet. 

You can deactivate the firewall in menu 21.2 or via the Business Secure Router 
embedded WebGUI. You can also define additional firewall rules or modify 
existing ones, but exercise extreme caution in doing so. See the chapters on 
firewalls in 

Nortel Business Secure Router 222 Configuration — Basics 

(NN47922-500)

 

for more information on the firewall.

Note: 

When the firewall is activated, the default policy can 

communicate to the Internet if the communication originates from the 
LAN, and blocks all traffic to the LAN that originates from the Internet.
