Choose tab "Installer" in the dialog that comes up and enter directory
where firewall script should be installed, the name of the account
used to manage the firewall and ip address 127.0.0.1 in the field for
the address used to communicate with the firewall. The directory
where Firewall Builder will install firewall script should exist
already; you may need to create it manually. We use root account to
install and activate policy. Make sure that root login via ssh is
permitted by your sshd configuration. We use loopback address because
the program will manage policy of the same machine it is running
on. Once done, click "OK" to save parameters.
Document Using
Built-in Policy Installer in Firewall Builder explains how to use
regular user account with sudo rather than root to install and
activate policy.
