Chargen/UDP 19 flooding on Win7

The easiest way on Win7 devices is to stop and disable the Simple TCP/IP services:
†

Start -> Run: services.msc
†

That opens the Services control panel.† Find Simple TCP/IP Services on the list.† Double-click for properties. Stop the Service (takes a few seconds), and then set the Startup Type to "Disabled."† Click OK to save changes.† No need to restart the Streambox.

†

Additionally one can create a firewall rule (Control Panel -> Security -> Windows Firewall -> Advanced settings) under both incoming and outgoing that blocks UDP port 19.

†

If you have one or more of the older Win XP Streamboxes, try this:

Open the Network Connections screen. Open the properties of the network adapter in use.

Select Internet Protocol TCP/IP Settings and click properties.

Click Advanced

Click the Options tab.

Select "TCP/IP filtering" and click properties.

Check the box to enable filtering, and then select "Permit Only" under UDP.† Add the following ports (reason for use in parenthesis):

1770 (default streaming)

2051 (file transfer)

2060 (legacy ABN)

5926 (IFB)
