Ihave a virgin super hub and would like to know what firewall settings to use?

I have a Virgin Media Super hub and would like to know what firewall settings to put it on, low, medium or high or whether it makes any difference? I am trying to make my network and Mac as secure as possible and need help, i've always had PCs.

The Mac operating system has very good firewall built-in to Apple menu -> System Preferences -> File Sharing.
That said, if your hub has 802.11g or higher WiFi, be sure to use WPA2 security, and see if there are settings to prevent ping attacks.
If your hub is only ethernet, find out what settings to ues to prevent ping attacks.
802.11b WiFi is fairly insecure, and you are better to use ethernet instead, if that's all it provides.
