When activated, the firewall allows all traffic to the Internet that originates from the LAN, and
blocks all traffic to the LAN that originates from the Internet. In other words the Prestige will:
Allow all sessions originating from the LAN to the WAN
Deny all sessions originating from the WAN to the LAN
LAN-to-WAN rules are local network to Internet firewall rules. The default is to forward all traffic
from your local network to the Internet.
