What is UPnP for?
- Hi list,
I've read that some of you got increased network performance/stability
when turning off UPnP. What is UPnP good for? I know it's used for
automatically open port on routers and so on but I use my NSLU2 on my
internal LAN only. Is there are good reason to have UPnP turned on?

- I'll take a stab at this. Feel free to correct anything I get
uPNP is a advertisement method for network services. As you
mentioned, one of its uses is to open ports on routers for
services. In the case of the NSLU2 I _think_ uPNP is used to
advertise the File Serving service to machines on the network. So
without you knowing the NSLU2 existed, it would potentially show up
in "My Network Places." You wouldn't have to do anything to get it
to show up there. I think one of the music serving services in
uNSLUng uses it to advertise itself too.
I know I have had uPNP disabled for the entire time I've been using
my NSLU2 and it works fine. Certainly works better than it did with
uPNP on, which would make it drop off the network when you tried to
access it. My guess is that there is another uPNP client on my
network and it and the NSLU2 are not getting along.
hope that helps,
