Manage Simple Outbound Firewall Rules for Services and
A firewall protects one network (the trusted network, such as your LAN) from another (the
untrusted network, such as the Internet), while allowing communication between the two.
The modem router provides one default outbound firewall rule: It allows all access to the
Internet (that is, the WAN). You can add simple rules to prevent access to specific services
and applications on the Internet. In addition, you can specify if a rule applies to one user, a
range of users, or all users on your LAN.
The modem router lists many default services and applications that you can use in outbound
rules. You can also add an outbound firewall rule for a custom service or application.
For information about blocking specific keywords, URLs, or sites, see Use Keywords to Block
Internet Sites on page 85. This type of blocking is another aspect of the outbound firewall.
For information about inbound firewall rules, see Manage Port Forwarding and
Port Triggering on page 172.
Note: Service blocking means the same as applying outbound firewall rules.
