What is firewall?
Firewall is a network security system based on specific hardware or software. It manages and controls incoming and outgoing network traffic based on a set of application rules. It controls the access of networks to maintain the security of your system and guards against threats from the online public interaction.

Another reason for using firewall is to block ads: If an app cannot access the Internet, it cannot display ads. However, if you are looking to block ads, you are better off going with AdFree Android because it works a lot better in blocking ads; with DroidWall users won’t be able to block ads from apps that need Internet access to be used.
