This program allows your device to be less vulnerable to possible external attacks, protecting the information you have on your server, so that it is only you who authorizes devices to link to your host computer when configuring this resource.

It is important to highlight that it is an action that must be done with calm and with the precaution of having read in advance the steps for its activation, > if you want to conserve both the resources of the main equipment and the security of its correct operation.
