View Full Version : People with firewalls can't see my station
8th June 2006, 22:46
Everyone can listen to my radio station at their home but can't listen to it at home. I can't even pull up my radio station from work. Could it be a firewall at people work places that's preventing them from listening or could it be something on my end?

I have no trouble from my home (your end is fine) -- It's more likely the player that is trying to listen -- beware of Windows media player -- Offices may block the standard SHOUTcast port (8000), or the protocol -- btw: port 8000 is used for many different things (that may be blocked or used for another purpose), so it's always a good idea to change it to something else [>10,000]. Your stream bitrate is 128kbps -- not everyone can handle that rate, but check your log for at least the connection succeeding. Users behind a proxy (AOL) may also have trouble.

you are not alone, any stream using port 8000 can be connected to from the office, school, or internet keyosk. However I can tune in if the stream is using a port that is open through I firewall. I made a stream run on port 8080 which is used by http proxy and happens to be opened on my firewall . I have other streams that were setup to run on port 80 (standard web) , you will see that being the case as well with the comerical streaming stations they run on tcp port 80 .

What firewall software are you using?.

corporate firewall are hardware firewalls not software on a windows XP box.
the issue is a firewall at the office that doesnt allow the port in to their network that your stream runs on.
standard ports open on most corporate firewalls.

I am getting someone to test their 8080 port and 80 port at work to see if it's open. And hopefully that will solve my problem.

Beware that firewalls in general are bi-directional -- that is to say that they differentially block traffic in both directions -- so a closed inbound [from the internet] port 80 does not mean that port 80 is also closed oubound [from the LAN], but it may be -- moreover, depending on the level of technical sophistication of the firewall and it's config, an outbound port may be open to view a webpage, but blocked for a shoutcast stream, but not its station page.
The good ones [$$$$$] are smart enough to actually "see" the outbound request, recognize it as a request for a stream by a "known" media player [via the good old HTTP user-agent [A:] header], and drop the request before it ever leaves the LAN.
Residential broadband routers are seldom confgured to block outbound access, but many have the elementary ability to block ports or protocols from the inside (sometimes disguised as parental controls). You find these in the homes of the overly paranoid.
