In response, the browser receives a set of data and code that downloads and displays a web page.
For this reason, the most popular protocols reserved ports in the range from 0 to 1023.įor example, carrying out surfing on the Internet, your browser connects to port 80 on a remote server that hosts the site. It is worth noting that the client program should always know the port to which it needs to connect to a remote server or another network device. Any other port can not be opened, respectively, and check too. Ports are identified by numbers from 0 to 65535, inclusive. If the network cable will come with data port number 1234 - that to me." In human language it would sound something like this: "I, the server program, open port 1234. If a program or service plans to work with the network, it opens the port with a unique number, through which it can work with remote clients / servers. Ports that virtual address on your computer or network device which enables it communicate with other computer or devices. Use your public ip and test the ports which you have configured to block from your firewall. In case you have set up DMZ host and you want to test whether your firewall is effective of not, same can be verified by port checker tool. All your open ports must be accessible from the Internet (of course, if you have a dedicated IP). If your computer is connected to the Internet directly (without a router / router), then perform port forwarding is required. However, outside of the Internet, connect to your server without port forwarding will not work.
