13.3.1 LAN-to-WAN rules
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.
How can you block certain LAN to WAN traffic?
You may choose to block certain LAN-to-WAN traffic in the Services screen (click the
Services tab). All services displayed in the Blocked Services list box are LAN-to-WAN
firewall rules that block those services originating from the LAN.
Blocked LAN-to-WAN packets are considered alerts. Alerts are “higher priority logs” that
include system errors, attacks and attempted access to blocked web sites. Alerts appear in red
in the View Log screen. You may choose to have alerts e-mailed immediately in the Log
Settings screen.
LAN-to-LAN/Prestige means the LAN to the Prestige LAN interface. This is always allowed,
as this is how you manage the Prestige from your local computer.
Packets to Log Choose what WAN to LAN and WAN to WAN/Prestige packets to log. Choose
from:
No Log
Log Forwarded (see how to forward WAN to LAN traffic in the next section)
Log All (log all WAN to LAN packets).
