I have a Hotbrick hardware firewall for the trading machine... I whitelist it, only a few url's are open to the computer and all others are blocked.. I have the home page on the browser set to something that should be blocked. This morning I open the browser to manage the whitelist and discover that I can access the whole, wide www world! I checked the Hotbrick, it should be whitelisting, I try blacklisting and it's still open to the whole wide www world... I had to do the physical reset with the reset button on the Hotbrick and reenter the whitelist to get it working again... whether it got hacked or a power glitch just messed it up, I don't know.. but I don't like it..... the other choices are SonicWall and Cisco I guess... I hate Cisco, if you aren't a PhD in computer science you can't even navigate their website let alone set up the firewall.. maybe Sonic is better?
