I double checked inbound connects to port 843 from the remote work station at work. My firewall shows the active connection (with telnet) and so does netstat. It must be something with sc_trans?
How do I locally test that port? Simple HTTP request or something else?
I just turned off my firewall, try again.
I just found a way, lol. Tested it from linux box on the network:
root@homeserver:~# python -c 'print "<policy-file-request/>%c" % 0' | nc 192.168.2.187 843
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<!-- Set shoutcast ports -->
<allow-access-from domain="*" to-ports="843,80,64846,64848,64850,64852"/>
...and from my work linux server on a completely different IP/network. Same result.
