DESCRIPTION
This setting blocks all traffic to and from the Internet. Only local network traffic and
LAN to WAN service (Telnet, FTP, HTTP, HTTPS, DNS, POP3, SMTP) is permitted.
This is the recommended setting. It allows traffic to the Internet but blocks anyone
from the Internet from accessing any services on your local network.
This setting allows traffic to the Internet and also allows someone from the Internet
to access services on your local network or the management interfaces on your
router (when configured in Remote MGMT). This would be used with Port Forwarding,
Default Server.
This setting allows the customer to create and edit individual firewall rules.
