2. Application-level gateway - Wikipedia

   en.wikipedia.org/wiki/Application-level_gateway

   An application-level gateway ( ALG, also known as application layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network. [1] [2] It allows customized NAT traversal filters to be plugged into the gateway to support address and port ...

3. Port forwarding - Wikipedia

   en.wikipedia.org/wiki/Port_forwarding

   Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.

4. Network address translation - Wikipedia

   en.wikipedia.org/wiki/Network_address_translation

   IP addresses and port numbers are encoded in the payload data and must be known before the traversal of NATs. Without special techniques, such as STUN, NAT behavior is unpredictable and communications may fail. Application Layer Gateway (ALG) software or hardware may correct these problems. An ALG software module running on a NAT firewall ...

5. NAT traversal - Wikipedia

   en.wikipedia.org/wiki/NAT_traversal

   NAT Port Mapping Protocol (NAT-PMP) is a protocol introduced by Apple as an alternative to IGDP. Port Control Protocol (PCP) is a successor of NAT-PMP. UPnP Internet Gateway Device Protocol (UPnP IGD) is supported by many small NAT gateways in home or small office settings. It allows a device on a network to ask the router to open a port.

6. Stateful firewall - Wikipedia

   en.wikipedia.org/wiki/Stateful_firewall

   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.

7. IPv6 transition mechanism - Wikipedia

   en.wikipedia.org/wiki/IPv6_transition_mechanism

   NAPT-PT. v. t. e. An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable, transition ...

8. Port Control Protocol - Wikipedia

   en.wikipedia.org/wiki/Port_Control_Protocol

   Port Control Protocol ( PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering. By allowing hosts to create explicit port forwarding rules, handling of ...

9. Hole punching (networking) - Wikipedia

   en.wikipedia.org/wiki/Hole_punching_(networking)

   Hole punching (or sometimes punch-through) is a technique in computer networking for establishing a direct connection between two parties in which one or both are behind firewalls or behind routers that use network address translation (NAT). To punch a hole, each client connects to an unrestricted third-party server that temporarily stores ...
