How to Change a Firewall in a Motorola Modemby Michelle Varsallona
Motorola brand modems do not come with their own built-in firewall. Instead, you must use the Windows firewall to configure what passes through the modem. The Windows firewall uses basic program and port settings. Even though you control the settings through the Windows operating system, it allows or disallows programs and ports from passing through your modem's firewall.
Click "Start" and select the "Control Panel."
Click on "Security" and select "Windows Firewall."
Click the "Change Settings" link.
Turn the firewall on or off in the "General" tab. In the "Exceptions" tab, configure which programs the firewall allows through and which programs the firewall blocks. In the "Advanced" tab, you can reset the firewall and change the network connections that you want to protect.
Click "Apply" and "OK" to save and close the window.
