— Router. Routers with traditional functionality — in other words, devices that are not related to firewalls (see below). The main function of the router (router) is to transmit data packets to certain addresses based on the rules specified in the settings. A similar function is performed by switches ; however, routers operate at a higher level of the OSI network model — the third — and are responsible for logical rather than physical routing, usually using the IP protocol of one version or another (IPv4, IPv6). Routers are widely used to build local networks, to provide access to the Internet, as well as to interconnect individual "locals". Note that such equipment may have separate security features (antispam, antivirus, etc.), but such models are rare, and such functionality is more modest in them than in firewalls.

— Firewall. A specialized type of router, the main feature of which is advanced filtering and traffic processing capabilities, as well as additional security features. The official name of such devices is “firewalls”, which quite accurately describes the main way they are used: filtering traffic between the serviced network and the rest of the environment (both neighboring “LANs” and the Internet). All firewalls must have protection against DoS attacks and content filtering (see "Security"); most often, other security features are also provided, but...their set should be specified separately.
Note that a firewall can also be created purely by software — for example, on one of the computers on the local network, which plays the role of an intermediate node. However, it is easier and more reliable to use specialized equipment for this: separately made firewalls are easier to configure, and their hardware is initially optimized for the corresponding tasks.

How the router connects to the Internet or other external network.

Almost all modern routers have ethernet network connectors for this purpose, however, in addition to them, other connection options can be provided — both wired ( ADSL, SFP / SFP + optics) and wireless (mobile access via 3G / 4G modem or SIM card). Here are the features of each option:

— Ethernet. A standard LAN network cable connector (“twisted pair”) is the most popular modern wired connection format in computer networks. Widely used both in "local" and to provide access to the Internet. This standard is somewhat inferior to SFP / SFP + (see below) in terms of speed and noise immunity, but it is much cheaper. The speed of work in modern versions of Ethernet can reach 10 Gbps (see "Connection speed of WAN ports"), theoretically, a further increase in throughput is possible.

— SFP / SFP + (optics). A connector for transmitting network traffic over a fiber optic cable. The main advantage of such a cable is complete insensitivity to electromagnetic interference. And data transfer rates can reach 2.7 Gbps in the original SFP and 16 Gbps in SFP+. At the same time, maintaining this standard is not cheap, and the benefits mentioned are not often needed in fact. Therefore, SFP / SFP + is found mainly...in mid-range and top-level routers.

— ADSL. Connecting to the Internet through a fixed telephone network using ADSL technology. The key advantage of this connection is the ability to use existing networks without laying additional wires; at the same time, Internet access is completely separated from telephone communication and traffic does not interfere with voice calls. On the other hand, the bandwidth of ADSL is very low by modern standards (less than 24 Mbps), moreover, the data transmission speed is noticeably lower than the reception speed. This can create problems for video communication and some other specific tasks. So nowadays ADSL is used less and less.

— 3G/4G modem (USB). Internet connection via mobile network using a separate 3G or 4G modem connected to the USB port. This feature can be useful where there is no full-fledged wired connection (for example, in rural areas), and also as a fallback option in case the main communication channel fails. And the type of network supported depends mainly on the modem used (the compatibility of the router with different models needs to be specified separately, but most often there are no problems with this). As for specific types of networks, most 3G modems work in UMTS networks (the same ones that are massively used by mobile phones); the data transfer rate in such networks can reach 75 Mbit / s (however, usually it is much lower). Less common are 3G modems for EV-DO networks based on CDMA — this standard has lower speeds (up to 14.7 Mbps) and not as extensive coverage as UMTS, however, both the equipment and the connection itself can be cheaper. And the designation "4G" means only one type of networks — LTE; it provides speeds up to 173 Mbps, but is not as widespread as 3G.

— SIM card. Another option for connecting to the Internet via mobile networks is its own SIM card slot provided in the design of the router. This option is convenient because you do not need to buy an additional device (modem) for mobile Internet — you just need to purchase an operator's SIM card. On the other hand, due to the built-in mobile communication modules, such routers themselves are more expensive than analogues for USB modems. In addition, the connectivity options in them are limited by the characteristics of the module: for example, a router for 3G networks will not be able to fully use 4G networks (whereas a USB modem can usually be changed to a more advanced one). As a result, this option is relatively rare in modern equipment.

The number of standard Gigabit Ethernet RJ-45 network connectors provided in the device design.

As the name suggests, these connectors provide data transfer rates up to 1 Gbps. Initially, Gigabit Ethernet was considered a professional standard, and even now the real needs for such speeds arise mainly when performing special tasks. Nevertheless, even relatively inexpensive computers are now equipped with gigabit network adapters, not to mention more advanced technology.

As for the number of connectors, it corresponds to the number of network devices that can be connected to the "switch" directly, without the use of additional equipment. At the same time, it is worth noting that in some "switches" individual connectors of this type are combined with optical SFP or SFP +. Such connectors are marked "combo" and are taken into account both when counting RJ-45 and when counting SFP / SFP +.

The number of ports designated as WAN by the manufacturer. They are intended for wired connection of the device to the Internet or other external networks (to solve some specific problems).

In this case, dedicated LANs mean directly marked network connectors designed for wired connection of LAN devices - PCs, servers, additional access points, etc. The number of ports corresponds to the number of devices that can be directly connected to the equipment by wire.

The number of WAN/LAN combo ports specified by the manufacturer in the device design that can be reassigned to work with both an external WAN and a local LAN. Such a solution allows to reduce the total number of connection ports and at the same time expand the functionality of the equipment for flexible adaptation to user needs.

The number of USB ports provided in the design of the router. USB is a universal interface used in computer technology to connect peripheral devices for various purposes. One of its uses is to connect a 3G modem (if provided, see “Data entry (WAN-port)”), but this is not limited to this: in fact, the options for using USB ports directly depend only on the capabilities specified in the router firmware. So, in some models, you can connect a flash drive or an external hard drive to this connector — to update the firmware or even organize an FTP server directly on the router. And for other peripherals — printers, cameras, etc. — USB connection can be used to work as network devices (however, such functions are rare in standard firmware).

The presence of a console port in the router. This connector is used to control the device settings from a separate computer, which plays the role of a control panel — a console. The advantage of this format of operation is that access to the functions of the router does not depend on the state of the network; in addition, special utilities can be used on the console that provide more extensive capabilities than a regular web interface or network protocols (see "Management"). An RS-232 connector is often used as a console port, but in modern routers this role can also be played by a separate Ethernet input (not used for any other purpose).

Management methods and protocols supported by the router.

— SSH. Abbreviation for Secure Shell, i.e. "Safe shell". The SSH protocol provides a fairly high degree of security, because. encrypts all transmitted data, including passwords. Suitable for managing almost all major network protocols, but requires a special utility on the host computer.

— Telnet. A network management protocol that provides configuration via a text-based command line. It does not use encryption and does not protect transmitted data, and is also devoid of a graphical interface, which is why in many areas it has been supplanted by more secure (SSH) or more convenient (web interface) options. However, it is still used in modern network equipment — in particular, as a means of managing FTP servers.

— Web interface. This function allows you to open the router's management interface in a regular Internet browser. Thus, to access the settings, you do not need special software — just a regular computer or even a smartphone / tablet is enough (modern mobile browsers are close to desktop ones in terms of capabilities).

— SNMP. Abbreviation for Simple Network Management Protocol, i.e. "simple network control protocol". It is a standard part of the common TCP/IP protocol on which both the Internet and many local networks...are built. It uses two types of software — "managers" on control computers and "agents" on managed computers (in this case, on a router). The degree of security is relatively low, but SNMP can be used for simple management tasks.

Note that this list is not exhaustive — some routers have other, more specific management capabilities (such as the EEM event manager in Cisco devices).
