This question is probably very basic to anyone familiar with hardware firewalls. Problem is that I'm definitely not in that category. I recently bought a TZ-150 model SonicWall firewall, but whenever I connect it to my Cable Modem (Zoom modem, Comcast is provider), I lose connection to the Internet (which is critical to my business, so worst-case scenario is that I'm just not going to use the SonicWall). I am a total "newbie" to this area of network/Internet connectivity and setting up a hardware firewall, so any help would be greatly appreciated. Frankly, I don't even know enough about this to ask any kind of specific question. All I do know is that the way the current firewall settings are configured in the TZ-150, I can't connect to the Internet. I'll provide screen prints and or any other information that anyone might need to enable you to help me out, but, at this point, I don't even know what screen shot would be of any use!
