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:

• In

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

• Outb

ound. 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 su

bjected 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.

 To set up firewall rules:

1. Select Se

curity > Firewall Rules to display the following screen:

2. To add an outbound rule, click Add under Outbound Services.
