Manage Simple Outbound Firewall Rules for Services and
Applications
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.
