It wouldn't matter much anyway because the broadcasting software talks to the proxy server on port 8080 and then the proxy server talks to rr.com on port 80. All http traffic has to go through port 8080 to get to the outside world.... I honestly don't know if RR still accepts connections on that port.
Thanks for the reply Peter, I really appreciate it.Just specify 8080 as the server port, and you should be all set.
ScannerCast: Hello proxy.tld.com on port 8080, I have traffic that I need you to relay to radioreference.com on port 80.
Proxy: Rock on dude, I can take care of that for you because that is just how I roll.
Proxy: Yo. radioreference.com .. sup bro. I have some traffic for you on port 80.
Radioreference.com: Thanks homefry, I'll add this to my collection.
Proxy: Yo. ScannerCast. I delivered your traffic and radioreference.com told me to tell you sup.
ScannerCast: Cool. Here is some more traffic to the same place.
Proxy: wtf do I look like to you .. a proxy server? Gimme that traffic ... sheeesh.
