I put my patch for it in ftp://ftp.dqc.org/pub/qtss
Also the original code for apple's server is there

What is really nice about this daemon is that it does RTSP just like Real
Media's server, but it's *FREE*, no license fees for any number of users, and
it should work with any real G2 player or apple quicktime player, etc...

What happens? Connection times out? What does your configuration look like?

Using basic NAT,

(map ppp0 192.168.1.0/24 -> ppp0/32 portmap tcp/udp 10000:60000)

it works for me using the realaudio G2 client software from inside the
NAT....
