Nortel Business Secure Router 252 Configuration — Advanced
Basic setup complete
You have successfully connected, installed, and set up your Business Secure
Router
to operate on your network, as well as access the Internet.
If all your settings are correct, your Business Secure Router can connect
automatically to the Internet. If the connection fails, note the error message that
you receive on the screen and take the appropriate troubleshooting steps.
You can deactivate the firewall in menu 21.2 or using the embedded WebGUI in
the Business Secure Router. You can also define additional firewall rules or
modify existing ones, but exercise extreme caution in doing so. For more
information about the firewall, see
