Access server - router

 Access server - router



This type of network is most often called routing, in which case the server performs the function of an Internet conductor with its own hands, it is dominated by the presence of several network cards (we will refer to network cards as INTERNET and LAN in the future). The home server itself is connected to the Internet via the INTERNET card, and the second LAN card is connected to the local network, where it is necessary to distribute the Internet. The task of the server itself in this case is to direct traffic to exactly those addresses of computers (clients) that need it. The access server can limit the capabilities of clients, for example, if we need to give Internet access only to certain computers, while others on the same network are used only as local ones. This feature of limiting the client's network capabilities is called a Firewall.

Access Server

Restrictions can be both in terms of speed and the permission of the client's access to the Internet. The simplest example is a complete ban on Internet access, it can also be partial access, limited at the port level, which means that you can separately prohibit Internet access not only for a computer, but also for a separate program on this computer. Like a computer, each program has its own address on the network. The computer address is commonly referred to as an IP address, while the address of a client program is commonly referred to as a port.
