Enter user password when prompted.

2. After the installation is complete, click on ‘Menu>Internet>Firestarter’

3. Click ‘Forward’ to continue.

4. Select the interface which is connected to the internet. Select ‘Start the firewall on dial-out’ if you are using a modem. Also select the option ‘IP address is assigned via DHCP’, if applicable. Click ‘Forward’ to continue.

5. Select if you want to share your internet connection with other computers on the network and click ‘Forward’ to continue.

6. Select ‘Start firewall now’ and click ‘Save’.

7. Once the firewall starts, you can view the inbound, outbound events and the utilization/activity on the interface connected to the internet and also the active connections on the ‘Status’ tab.

8. Now click on ‘Edit>Preferences’
