Manage Port Filtering for Outgoing Traffic
Note: You can enable and manage port filtering only when the modem functions in
Router mode.
As an added security measure, you can specify which services and applications (for
example, HTTP, FTP, an email server) can access or are blocked from the Internet.
Before you add a service or application, first determine which port number and protocol
the service or application uses. You can usually find this information by contacting the
publisher of the service or application or searching the Internet.
The following sections provide information about managing port filtering for outgoing
traffic:

the Internet. All other services and applications are allowed to access the Internet.
Note: The blacklist and whitelist are mutually exclusive. You can enable either one or
the other.
IMPORTANT: For you to be able to set up a blacklist, the modem must be connected
to the Internet. If the modem is not connected to the Internet, the configuration fails.
