Figure 58   Firewall Rule Directions

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.

WAN to LAN

To log packets related to firewall rules, make sure that Access Control under Log 

is selected in the Logs, Log Settings screen.

Packets to Log
