   Windows Routing and Remote Access Service is a feature that can be installed on Windows (mainly server) Operating Systems, and can perform routing functions, NAT, and implement firewall rules. Zentyal (formerly eBox Platform) Active: Ubuntu derivative: x86, x86-64: Open source: Free with paid services available

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. Application-level gateway - Wikipedia

   en.wikipedia.org/wiki/Application-level_gateway

   In order for these protocols to work through NAT or a firewall, either the application has to know about an address/port number combination that allows incoming packets, or the NAT has to monitor the control traffic and open up port mappings (firewall pinholes) dynamically as required. Legitimate application data can thus be passed through the ...

5. Network address translation - Wikipedia

   en.wikipedia.org/wiki/Network_address_translation

   source NAT is a common expansion and is the counterpart of destination NAT (DNAT). This is used to describe one-to-many NAT; NAT for outgoing connections to public services. stateful NAT is used by Cisco Systems [22] static NAT is used by WatchGuard [23] secure NAT is used by F5 [24] and by Microsoft (in regard to the ISA Server)

6. NAT Port Mapping Protocol - Wikipedia

   en.wikipedia.org/wiki/NAT_Port_Mapping_Protocol

   NAT Port Mapping Protocol (NAT-PMP) is a network protocol for establishing network address translation (NAT) settings and port forwarding configurations automatically without user effort. [1] The protocol automatically determines the external IPv4 address of a NAT gateway, and provides means for an application to communicate the parameters for ...

7. 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.

8. Gateway (telecommunications) - Wikipedia

   en.wikipedia.org/wiki/Gateway_(telecommunications)

   A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks [1] [2] and can operate at any of the seven layers of the OSI model.

9. Amazon Elastic Compute Cloud - Wikipedia

   en.wikipedia.org/wiki/Amazon_Elastic_Compute_Cloud

   Instance-store volumes are temporary storage, which survive rebooting an EC2 instance, but when the instance is stopped or terminated (e.g., by an API call, or due to a failure), this store is lost. The Amazon Elastic Block Store (EBS) provides raw block devices that can be attached to Amazon EC2 instances. These block devices can then be used ...
