Custom Port Filtering - Samsung SCH-LC11 User Manual

Custom Port Filtering

This screen allows you to define and enable custom Port Filtering
applications. You need to know details of the traffic used and
generated by the applications you wish to define. In particular,
you need to know the port numbers and the protocol (TCP, UDP)
used by outgoing traffic.
Custom Applications
Checkbox
Use this to enable an application after you have defined it. If
enabled, then traffic from this application is allowed to access
the Internet. Otherwise, the traffic is blocked.
Note: This checkbox has no effect unless the Port Filtering feature is
enabled.
Application Name
Enter a suitable name for the application you are defining.
Ports Link
Click this link to display the Port Definition panel, allowing you to
define the ports used by this application.
Each application has its own set of ports.
Click Hide when finished defining the current application.
Click Apply when finished defining all applications.
Port Definition Panel
This panel is displayed when the Ports link is clicked, and allows
you to define the ports used by each application. Background
shading indicates the current application whose ports are being
defined. You can define up to 5 port ranges (rows) for each
application. Unused rows should be left blank.
Start Port - End Port
These fields are used to define the ports used by the application
you are defining. These ports refer to outgoing traffic.
For a single port, enter the port number in both the Start Port and
End Port fields.
For a port range, enter the beginning of the range in the Start Port
field and the end of the range in the End Port field.
Up to 5 ports or port ranges can be defined. Use as many rows as
necessary; unused rows can be left blank.
Protocol
For each port range (each row), select the protocol (TCP, UDP, or
both) used by that port range.
