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 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 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.
