In this window you can access information related to security, define / change new rules and security

mechanisms, namely:

• Uniform Resource Locator (URL) filter.

You can set URL addresses, which are not accessible from the local network.

• Firewall and DMZ.

Firewall is an application that controls all incoming and outgoing accesses to the communication ports

of the TCP and UDP transport protocols. It is therefore possible to block or unblock these ports for any

of the transport protocols.

A DMZ or demilitarized zone (DMZ), also known as a perimeter network, is a physical and/or logical

subnet that contains and exposes an organization's external border services to a larger, unreliable

network, typically the Internet. Any devices in this area, that is, between the trusted network (usually the

local private network) and the untrusted network (usually the Internet), are in the demilitarized zone. The

function of a DMZ is to keep all services that have external access (such as HTTP, FTP, e-mail servers,

etc.) together on a local network. To achieve this goal, computers in a DMZ must not contain any form

of LAN access.
