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.
