antinode please ignore my request for instructions on how to disable UPnP. I found it Advanced setup->UPnP and one click disables it.

Feeling more secure in my little network.

Don't you think this is a serious issue? Shouldn't this be disabled by default?

With this enabled it would be very easy for malware to set up a remote bot network.

       What I think matters little.

     

       It's a convenience feature for users who expect everything to just,
    uh, "plug 'n' play".  I'm sure that it's widely liked (and
    little-noticed).  It does allow an application (rogue or friendly) to
    enable incoming connections without your explicit permission.

     

    > [...] Shouldn't this be disabled by default?

     

       I always ensure that it's disabled on my stuff.

     

       I don't see it listed among the "Factory default settings" in the
    User Manual (yours or mine (D7000)), which I'd call an oversight, at
    best.

     

       The usual threats are explicit port forwarding/triggering, DMZ
    server, and UPnP.  Only UPnP could be enabled by default (because only
    it is automatic enough).

      Me, I'm old fashion. I don't like things happening auto-magically. I like to explicitly make them happen or not.

      Thanks to you. I turned off UPnP and I'm investigating the server my camera was talking to.

      The camera, like almost everything else, is made in China. I'm going to really check out this supposed streaming video server.

      I personally have done a lot of business with China. The Chinese are great people, but their ethics in business are very much "if you can do it, do it". If you get caught you can always apologize after the fact.
