FIREWALL/ROUTER (Fortigate 61F)

Firewall: security device that analyses and can block Internet Protocol (IP) communications according to specified rules between different networks (for example between Internet and a local network).

Router: intelligent hub used as a gateway between various networks.

In small networks, the firewall is generally embedded into the router. Some models are even modems as well (ADSL, fiber, coaxial).

A firewall is a security device. It allows you to specify what types of information are allowed to leave a network (towards the Internet) and what types of information are allowed to enter a network (from the Internet).

Inside a local network, all information coming from and going to the internet goes through the firewall. It is therefore the device that provides the first line of protection against possible attacks coming from the internet.

In small networks, the firewall is generally combined with a router which allows information to be relayed between several different networks, for example your local network and the Internet.

Some ADSL modems can also act as routers.

Open article, with at least the following specifications:

• Gigabit ethernet connections, including a four-port managed switch
• built in high-speed wireless access point
• IP security (IPsec) VPN for flexible remote access
• support for separate virtual networks and wireless guest access
• intuitive, browser-based device manager

Before changing the settings of a firewall/router, it is essential to back up its configuration so as to be able to return to it in case of a mistake.

Make sure the device is always powered (UPS) and protected from voltage fluctuations and surge.

Air must be able to flow freely around the device, especially in hot countries.

Should be out of reach of users.

Should be preferably grounded.

Ports should ideally be used only for connecting switches.

Avoid using more than one router on the same local network.

Must use HQ validated configuration.

Sizing is done according to how many users are connected to the router, the way they connect to it (through cable or wifi), the services and protocols used and also the number of Internet connections needed.
