CableCARD and Digital Cable vs Firewalls

Because I live in Canada, this topic doesn't mean too much to me. That said, for those of you that have Vista Media Center setup and have CableCard/Digital Cable Tuners, the CableCARD and Digital Cable FAQ might be useful to you.

In the past, I've written about the ports that need to be open for Media Center to operate in an optimal manner (Media Center Extenders vs Firewalls (MCE2005 and Vista) and Media Center Extender Setup and Windows Live OneCare: Issues and Resolutions). For those of you who have CableCard/Digital Cable Tuners, there are additional ports that need to be opened as per the above FAQ. See the below instructions for your firewall:

Windows Live OneCare 1.5: Use the firewall connection tool to allow the Windows Media Center ports to be available to the Digital Cable Tuner. To do this, follow these steps.

  1. Start Windows Live OneCare.
  2. In the left pane, click Change OneCare settings.
  3. On the Firewall tab, click Firewall connection tool.
  4. Click to select the Connect my XBOX 360 or Media Center Extender to my Media Center PC check box.
  5. Click OK, and then close the Windows Live OneCare Settings dialog box.
  6. Restart the computer.

Symantec Norton Internet Security 2007: Run LiveUpdate to install the latest signature files (released after January 31, 2007).

McAfee Internet Security Suite 2007: You will need to manually allow access to the system service port in the Firewall feature.

  1. Right-click the McAfee icon in the Windows system tray and click on SecurityCenter. On the Internet & Network Configuration pane, click Advanced.
  2. On the Firewall tab, click Firewall connection tool.
  3. On the Firewall pane, click System Services.
  4. Under Open System Service Port, select Universal Plug & Play (UPnP).
  5. Click OK.

Other Firewall Programs

If you have a firewall not listed above, try the following steps:

  1. Go to your firewall's settings option.
  2. Look for a list of applications that are allowed or prevented access to the Internet.
  3. Look for the applications listed in the table below. If it's designated as blocked or prevented access to the Internet, change the setting to allow access. If it's not listed at all, manually add it and allow access to the network.
  4. Save your changes and restart your firewall program.

If you configure a firewall after you install and configure your Digital Cable Tuners, you must manually configure the firewall to open the following ports.

ApplicationProtocol/PortDirectionNetwork
ehprivjob.exeUDP 5001-5006InboundLocal Subnet
svchost.exeUDP 1900Inbound, OutboundLocal Subnet
systemTCP 2869Inbound, OutboundLocal Subnet
ehprivjob.exeTCP 554OutboundLocal Subnet
ehprivjob.exeUDP 5757-5772OutboundLocal Subnet

The procedure that you use to manually configure these ports is different for each firewall model and for each firewall manufacturer. For more information about how to configure your firewall, see its documentation.

Hopefully this helps some people who have run into issues that might be caused by a firewall.
