  2. Configure Your Firewall: Once you have chosen a firewall, you need to configure it according to your network requirements. This involves setting up rules for inbound and outbound traffic.
  3. Test Your Firewall: After configuring your firewall, it is important to test it to ensure it is working as expected.
