While it is true, the vast majority of connection problems that occur when carrying out certain actions on the network or use a specific type of applications, are associated with the . Because any program or application that communicates over the Internet makes use of one or more ports to be able to send and receive information.
That is why, nowadays, much is said about the ability to open router ports for faster speed when a certain task is executed on the network. Such as making video conferences, using torrents or download applications, playing online, etc.
Thus, in order for you to know what this whole process is about through which you will make the most of a router, we have made this post. So here you will find the exact definition of the ports of a and what they work for, like the main types known today and also a complete list with each one that you can open in the router.
What are the ports of our router and what are they for?
Basically, an ADSL router refers to a device that has the ability to forward data packets from your computer between different networks or, it is defined as the person in charge of interconnecting computers that work within the framework of a certain network. Therefore, it works to establish the path that will be allocated to each data packet within any computer network.
In this sense, once you connect to a website, an external device or any service that has its own server, there is an exchange of data between said server and your computer. Which means that the only device that can handle that traffic is the router. Thus, when sending the information from your local network to the external one, the router makes use of a series of gates or channels in which all the content to be broadcast is organized.
Being these, the ports of the router that can be defined as those “virtual doors” or interfaces used by equipment connected to a network to support the input and output of data. Therefore, they are exemplified like some ports of ships that can be opened and closed to allow information to pass through a network. Consequently, slow download speed occurs around torrent or instant messaging programs.
Just like poor video conferencing quality or lag in online video games, it is claimed that These are problems caused by some router virtual doors being closed.. Since, these interfaces are the ones that are in charge of allowing the connection and are specific for certain actions. For this reason, there is the possibility of open the ports of the router to maximize its capacity.
What are the main types of ports that currently exist?
In general, two types of ports are distinguished with respect to the ADSL routers that are used today. Taking into account that each one of them is used by a host-to-host protocol to determine to which program, application, or higher-level protocol, all received messages should be transferred. Thus, the main classes of router interfaces that are known are: the (or “Transmission Control Protocol”) and udp ports (or “User Datagram Protocol”).
Here are its most interesting features:
TCP ports
In Spanish means “Transmission Control Protocol” and consists of one of the most fundamental protocols in the network. Thanks to the fact that TCP supports many of the applications used on the Internet by almost 100% of the people who access it, such as: web browsers, file sharing and application protocol (HTTP, SSH, FTP and SMTP).
Added to this, many software within a data structure made up of computer networks can make use of TCP ports to to create connections with each other from which a certain data stream can be transferred. Best of all, this protocol guarantees that this information will be sent to its destination without any error and in the same order.
Likewise, they are ports that are in charge of providing a mechanism for be able to differentiate several applications within the same machine and solely through the concept of “port”. It should be noted that the main purpose of TCP is that applications can communicate safely regardless of the lower layers. Also, offers remarkable flexibility in host-to-host connections and relieves system loadto a large degree.
UDP ports
It is the acronym for “User Datagram Protocol”, in Spanish; which is a connectionless protocol that works on IP networks. In this way, it is known as a simple data transmission protocol that is based on the exchange of datagrams, so accepts the sending of the same through the network without, before that, having established a connection. This is due to the fact that the same datagram adds sufficient addressing data in its header.
In addition to this, UDP ports are characterized by offering very few error recovery services and, instead, they only provide a direct way to send and get datagrams from a . Therefore, it is used when speed is the most important factor in data transmission, especially. Since, by its nature, it is much faster than TCP ports.
However, it should be distinguished that does not have acknowledgment or flow control, unlike TCP ports. Reason for which, the packages may be ahead of each other and it is not guaranteed that they arrive in the order indicated from the beginning, given that there is no confirmation of delivery or receipt. Considering that this class of ports were created with the objective to provide more speed in sending information with less stability and security requirements.
On the other hand, it is also necessary to distinguish that all routers have 65,536 ports in their entirety, which they are numbered from 0 to 65,535. In this way, the entity in charge of the global allocation of IP addresses and everything that concerns Internet protocols, known as IANA (“Internet Assigned Numbers Authority”), has proposed a port assignment standard and, for that reason, Today there are three categories of virtual doors that have a certain function.
Here, we specify the three existing groups:
Ports from 0 to 1023
Basically, they are the most recognized ports because are reserved for the operating system of the computer in question and, likewise, they deal with the most essential protocols to guarantee optimal operation. Thus, a clear example of this can be found in port 80 for the .
Ports from 1024 to 49151
In the second designated category, we find the registered ports that consist of those that are used exclusively by the applications and games that are installed on the machine. In this way, they are usually configured during their installation processes, automatically.
Ports from 49152 to 65535
These interfaces are known as “dynamic or private ports” and they refer to those that correspond to all those applications that must be connected to a server in order to function correctly. Among the clearest examples in this regard, we find P2P download clients.
List of all the ports that you can open on your Internet router
However, in order to take full advantage of the capabilities of your router, it will sometimes be necessary open a certain virtual door of it to enjoy a better connection speed for a certain activity. Which, in most cases, happens because said port has not been configured correctly and when you want to use a program or application, problems will arise.
The computer will not have knowledge about which door must be opened to the data to allow the passage of information and you also won’t know which application you should reissue them to. Consequently, downloads will be very slow or lag will occur in video games. Thus, it is recommended to open the interfaces of an ADSL router and, to be able to do it correctly, it is necessary to know which are each and every one of the ports of a router that can be started without any problem.
Therefore, below, we show you a complete list of them:
