Firewall Scripts
A firewall is any combination of hardware and software that secures a network and traffic to prevent
interception or intrusion. The router has built-in firewall capabilities to secure your network and data
communications. The router is equipped with predefined scripts that can be modified or used "as is" to
construct firewalls. All network security efforts, including firewall configurations, should be performed by an
experienced and qualified network security technician who is familiar with the unique architecture and
requirements of their network. Siemens Subscriber Networks cannot be liable for security violations due to
inadequate or incorrect firewall configurations.
To load a firewall script, perform the following:
1. Click Firewall Scripts on the left navigation pane of the Router Information page. This displays the Run a
Firewall Script page.
2. Select the desired Firewall Strength. This can be one of the following:
•
Maximum: Establishes a firewall with the most restrictive policies for maximum network security.
•
Medium: Establishes a firewall with flexible policies for a moderate level of network security.
•
Minimum: Establishes a firewall with a basic set of policies for a minimum level of network security.
•
None: No firewall is established.
3. Click Apply. This displays the firewall script in the Output Window.
