Security >> Firewall
Through this page, you can set whether to enable the input and output firewalls, and at the same time,
you can set the input and output rules of the firewall. Use these settings to prevent malicious network
access, or restrict internal users from accessing some resources of the external network, and improve
safety.
The firewall rule setting is a simple firewall module. This function supports two kinds of rules: input
rules and output rules. Each rule will be assigned a serial number, and a maximum of 10 each rule
can be set.
Taking into account the complexity of firewall settings, the following will illustrate with an example:

Port range
Port range
Src Address
The source address can be the host address, network address, or all
addresses 0.0.0.0; it can also be a network address similar
to *.*.*.0,
such as 192.168.1.0.
Dst Mask
The destination address can be a specific IP address or all
addresses 0.0.0.0; it can also be a network address similar to
*.*.*.0,
such as 192.168.1.0.
Src Port Range
This is the source address mask. When it is configured as
255.255.255.255, it means it is a specific host. When it is set as a
subnet mask of type 255.255.255.0, it means that the filter is a
network segment.
Dst Port Range
This is the destination address mask. When it is configured as
255.255.255.255, it means it is a specific host. When it is set as a
subnet mask of 255.255.255.0 type, it means that a network
segment is filtered.
