If you just press enter, I will assume you know what you are doing and not modify your DNS setup.

FIREWALLING


Please choose the firewall rules to use.
Note that these rules are very basic.
You are stronugly encouraged to use a more sophisticated firewall setup; however, these will provide basic security.
If you are running any servers on your machine, you must choose 'none' and set up firewalling yourself.
Otherwise, the firewall rules will deny access to all standard servers like Web, e-mail, ftp, etc.
If you are using SSH, the rules will block outgoing SSH connections which allocate a privileged source port.

The firewall choices are:
0-NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine.
