| | Port (computing) - Wikipedia, the free encyclopedia |
 | | A network port is a special number, ranging from 0-65535, recognized by the TCP and UDP protocols. | | | In computing, a port is a connection through which data is sent and received. | | | Hardware port trunking (HPT) is a technology that allows multiple hardware ports to be aggregated into a single group, effectively creating a single connection with a higher bandwidth. |

| | Port Forwarding Explained |
| | Port Forwarding is the technique of taking packets destined for a specific TCP of UDP port and machine, and 'forwards' them to a different port and/or machine. | | | Imagine that we want to port forward traffic to TCP port 80 on machine G to port 80 on another computer on the internet (I). | | | Packets from the LAN (A and B) would go to port 80 on the gateway (G), and then Guidedog would forward the packets on to their new destination, the machine (I) on the Internet. |

| | Port Address Translation enabled - NAT treats the client's IP address and TCP or UDP port number as a single entity, and uniquely maps that entity to another entity consisting of an IP address and TCP or UDP port number. | | | In this example, the Layer 3 Switch is configured to perform dynamic NAT to translate between the private addresses in the 10.10.10.x/24 sub-net and the Internet addresses in the 209.157.1.x/24 sub-net. | | | The following commands configure an IP address on virtual interface 15, which is the interface to the Internet access router, and enable outside NAT on the interface. |

| | NAT & Port Forwarding |
| | There are 65,331 port numbers which can also be further specified as either TCP or UDP [however for the purposes of this article this distinction is not important]. | | | A port can be thought of as a part of the IP address which enables a device with a single IP address to handle several different processes simultaneously. | | | When a port is forwarded, a table is created in the router which allows the request directed at port number XXXX to be 'forwarded' to a port attached to an 'internal IP address' found on one of the network's PCs, as specified by a port-forwarding rule. |

| | NAT: Traditional IP Network Address Translator (Network Address Translation) RFC 3022 |
| | Network Address Port Translation, or NAPT is a method by which many network addresses and their TCP/UDP ports are translated into a single network address and its TCP/UDP ports. | | | This solution has the disadvantage of taking away the end-to-end significance of an IP address, and making up for it with increased state in the network. | | | Basic Network Address Translation (Basic NAT) is a method by which IP addresses are mapped from one group to another, transparent to end users. |

| | Port forwarding - AzureusWiki |
| | Thus, you need to forward one listening port for Azureus and tick both the TCP and the UDP boxes, or make an extra rule, one for each protocol. | | | The only time you will notice the ports is when they are closed; no data is transmitted and you get error messages like "NAT Error." This usually happen because of firewalls and routers. | | | This is almost certainly caused by incorrectly forwarded ports from your router or firewall. |

| | CastleCops - UDP Port Scanner |
| | Unlike TCP, if the server (this case our scanner), sends a UDP packet to your system and doesn't receive a response then because of the nature of UDP, the scanner assumes your port(s) open. | | | Your system should then send back UDP replies stating the ports are closed, and the test results should properly reflect that. | | | The greater the selection of ports to scan, the greater chances of network failure exist. |

Checks ALL 65,535 x 3 communication ports: server and client TCP/IP and UDP in minutes. | | | If that port is connected to another computer, it will let you know what the computer's name and/or IP address is. It also will give you more information about the port that is open. | | | Port Scanners (Not to be used against other systems!) |

| | Using Address Translation |
| | Dynamic address translation is able to handle the TCP, UDP and ICMP protocols with a good level of functionality since the algorithm knows of values that can be adjusted to become unique in the three protocols. | | | Address translation does not in and of itself provide any greater level of security, but it can make it more difficult for intruders to understand the exact layout of your protected network and which machines are susceptible to attack. | | | Such translations are transpositions, that is, each address or port is mapped to a corresponding address or port in the new range, rather than translating them all to the same address or port. |

| | When the response was returned to to 206.124.146.179, it rewrote the destination IP TO 172.16.1.10 and forwarded the packet to 172.16.1.10 who no longer had a connection on UDP port 2857. | | | If you are seeing closed TCP ports other than 113 (auth) then either you have added rules to REJECT those ports or a router outside of your firewall is responding to connection requests on those ports. | | | Answer: The first example in the rules file documentation shows how to do port forwarding under Shorewall. |
