1) update to the current DNAS release, as that is from over 4 years ago and pretty much doesn't work correctly when it comes to being listed. see

2) you need to ensure that port 80 is opened in any router and firewall so the YP servers can see your stream. until that happens, the stream will not be listable and most people will not be able to access it. see
http://wiki.shoutcast.com/wiki/SHOUTcast_YP_Nak_Errors for more information (which is the link provided in the log output on newer DNAS than what you're using).
there's also a lot of other threads about this from over the years and is one of the things you need to do when doing any sort of streaming i.e. ensuring the server can access the internet and can be seen.
3) please check where you're posting a new thread. I've now moved this into the SHOUTcast section from the Winamp section.
