Firewall Rules to Control Network Access

Your modem router has a firewall that blocks unauthorized access to your wireless network 
and permits authorized inbound and outbound communications. Authorized communications 
are established according to inbound and outbound rules. The firewall has the following two 
default rules. You can create custom rules to further restrict the outbound communications or 
more widely open the inbound communications:

. Block all access from outside except responses to requests from the LAN side.

. Allow all access from the LAN side to the outside.

Set Up Firewall Rules

The Firewall Rules screen lets you configure custom rules to make exceptions to the default 
rules. Exceptions can be based on the service or application, source or destination IP 
addresses, and time of day. You can log traffic that matches or does not match the rule and 
change the order of rule precedence. 

All traffic attempting to pass through the firewall is subjected to the rules in the order shown in 
the Rules table from the top (highest precedence) to the default rules at the bottom. In some 
cases, the order of precedence is important to determine which communications are allowed 
into or out of the network.
