Firewall Rules
Firewall filtering restricts connection parameters to limit the risk of intrusion. The
firewall settings allow you to define a sequential list of rules that filter traffic based
on source and destination IP addresses and ports. Ingress packets are tested
against the filter rules one by one. As soon as a packet matches a rule, the
configured target action is implemented.
One rule, “Allow-Ping,” is pre-configured to allow Ping packets from the Internet.
You can enabl
e or disable this rule, but it cannot be modified or deleted. Click the
“
Add new” button to add a new firewall rule.
