Figure 58 Firewall Rule Directions

14.3.1 LAN-to-WAN rules

LAN-to-WANrules 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-WANtraffic in the Services screen (click the Services tab). All services displayed in the Blocked Services list box are LAN-to-WANfirewall rules that block those services originating from the LAN.

Blocked LAN-to-WANpackets 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.
