A next-generation firewall (NGFW) is a part of the third generation of firewall technology, combining a conventional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI) and an intrusion prevention system (IPS).
There are numerous third-party software applications for iptables that try to facilitate setting up rules. Front-ends in textual or graphical fashion allow users to click-generate simple rulesets; scripts usually refer to shell scripts (but other scripting languages are possible too) that call iptables or (the faster) iptables-restore with a set of predefined rules, or rules expanded from a ...

In computer networking, egress filtering is the practice of monitoring and potentially restricting the flow of information outbound from one network to another. Typically, it is information from a private TCP/IP computer network to the Internet that is controlled.
A virtual firewall then is a firewall service or appliance running entirely within a virtualised environment — even as another virtual machine, but just as readily within the hypervisor itself — providing the usual packet filtering and monitoring that a physical firewall provides.
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on configurable security rules. [1] [2] A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet, [3] or between several VLANs.
A personal firewall differs from a conventional firewall in terms of scale. A personal firewall will usually protect only the computer on which it is installed, as compared to a conventional firewall which is normally installed on a designated interface between two or more networks, such as a router or proxy server. Hence, personal firewalls ...
In computing, a stateful firewall is a network-based firewall that individually tracks sessions of network connections traversing it. Stateful packet inspection , also referred to as dynamic packet filtering, [ 1 ] is a security feature often used in non-commercial and business networks.
