About port forwarding and UPnP


Z

Zig

Hi everybody,

I'd like to know if it's necessary to enable UPnP on Windows' firewall
when UPnP is already installed on Windows, and when the the feature is
enabled on a P2P application (such as LimeWire, eMule or Shareaza) and
on the router. You know, when you open the settings window of the
firewall, within the Exceptions Tab, you have a check box for "UPnP
framework": does it need to be enabled as well? What's the purpose of
this firewall option?

The question also concerns Vista but I suppose it's the same on both
operating systems. Besides, as a side question: does the default install
come with UPnP or is it necessary to install it from the CD?

Thanks in advance.

Of course it would be way easier for me to check it myself instead of
bothering you with that, but it's just that currently I do not have
access to a computer with Windows XP SP2. I also took a look at
http://www.microsoft.com/whdc/device/media/upnp.mspx but it didn't
really help.

I don't believe it should be necessary to enable UPnP in the Windows
(sp2/sp3) firewall but you sometimes have to open UDP ports to enable
peer-to-peer programs to work properly. The main thing is to enable port
forwarding.

I forgot to add that the p2p program(s) should each be added as an exception
to Windows XP (sp2/sp3) firewall. Then you may not need to open any ports
manually at all.
