Настройка брандмауэра

A firewall sits between your computer and the network, and determines which resources on your computer remote users on the network are able to access. A properly configured firewall can greatly increase the out-of-the-box security of your system.

Выберите подходящий для вашей системы уровень безопасности.

No Firewall - No firewall allows complete access and does no security checking. It is recommended that this only be selected if you are running on a trusted network (not the Internet), or if you plan to do more detailed firewall configuration later.

If you are connecting your system to the Internet, but do not plan to run a server, this is the safest choice. If additional services are needed, you can choose Customize to allow specific services through the firewall.

Allow Incoming - Enabling these options allow the specified services to pass through the firewall. Note, during a workstation-class installation, the majority of these services are not present on the system.

Mail (SMTP) - This allows incoming SMTP mail delivery. If you need to allow remote hosts to connect directly to your machine to deliver mail, enable this option. Do not enable this if you collect your mail from your ISP's server by POP3 or IMAP, or if you use a tool such as fetchmail. Note that an improperly configured SMTP server can allow remote machines to use your server to send spam.

It is not recommended to enable this for devices that are connected to public networks, such as the Internet.
