Detailed explanation-1: -A virtual firewall runs entirely within a virtualized environment and provides the same security and inspection capabilities as a hardware firewall. It monitors and inspects network traffic between VMs and between VMs and the outside world.

Detailed explanation-2: -Stateful firewalls are capable of monitoring and detecting states of all traffic on a network to track and defend based on traffic patterns and flows. Stateless firewalls, however, only focus on individual packets, using preset rules to filter traffic.

Detailed explanation-3: -There are mainly three types of firewalls, such as software firewalls, hardware firewalls, or both, depending on their structure. Each type of firewall has different functionality but the same purpose.

Detailed explanation-4: -Filtering traffic via a firewall makes use of pre-set or dynamically learned rules for allowing and denying attempted connections. These rules are how a firewall regulates the flow of web traffic through your private network and private computer devices.
