3.6.4 Firewall
Firewalls are used to prevent unauthorized Internet users from accessing
private networks connected to the Internet, especially intranets. All
messages entering or leaving the intranet pass through the firewall, which
examines each message and blocks those that do not meet the specified
security criteria.
In order to ensure the safe operation of the system, we suggest to enable
and configure firewall. More detailed configuration and other safety related
configuration, please refer to
