Firewall Considerations

If there is a firewall between the server hosting the HPCA Console and your remote devices, you must ensure that the appropriate ports are open.

Windows Remote Desktop Connection requires TCP port 3389.

By default, Windows Remote Assistance requires TCP port 3389 when connecting to Windows XP or Windows Server 2003 target devices. It requires port 135 (the DCOM port) when connecting to Windows Vista, Windows Server 2008, Windows 7, or Windows 8 devices.

VNC requires TCP port 5800 for the initial connection. In addition, it requires TCP ports 5900 + [as many ports as necessary, depending on the type of systems involved]. For example:

Similarly, the Java VNC viewer requires TCP ports 5800 + [as many ports as necessary, depending on the type of systems involved].
