How To Port Forward To Stream Audio - SA540

[WTIJ]

Hello,

If anyone could provide a detailed, step-by-step process on how to set-up port forwarding so I can stream audio outside of the local network I would greatly appreciate it.

I took over a small radio ministry and am trying to get streaming started.

I am able to access our radio computer on the local network by inputting the computer's IP address and port into iTunes.

Currently, I am unable to access the same stream outside the network.

I know I need to change settings and enable port forwarding, but I need help.

I thought I had updated/changed the proper settings, but it will not work.

If anyone can help, please provide details as to what I need to do from start to finish.

Thanks in advance.

It depends on how you access the local network from the outside. It might be easiest if you post the configuration of your SA540. In the meantime, I assume you have already checked the administration guide ?

What configuration do you want me to post and where do I find that it?

How many ways are there to access the LAN from the outside?

[Georg Pauwen]

Hello,

I thought there was a command line that you could use, but there isn't. My bad...

What I meant was: do you access the local network through a VPN (browser, VPN client, etc.) ?

[WTIJ]

From within the network, I use a browser to get to the server settings and to browse online.  I use FileZilla to download/transfer programs and music and I use iTunes to stream.

I do not know how to access the audio stream from outside the network.

Is there a way to use iTunes or a similar program to get access to the audio stream?

That is all I want to do and need to do.  That is all someone from the outside needs access to.

Hello,

does the SA540 already have a public IP address on the outside ? If that is the case, you could configure a DMZ and allow access to the audio stream by configuring outbound and inbound rules. Check the attached document and look at pages 61 and 103.

[WTIJ]

Thanks for the reply.

What do I use as my IP address for the DMZ?

Once everything is set up, how do I direct users to the audio stream?  What do they type into their browser?

[Georg Pauwen]

Hello,

you would use a public IP address for the DMZ. In the document I mentioned before, go to page 30, there is a drawing that shows the addressing scheme for the DMZ setup.

http://www.cisco.com/c/dam/en/us/td/docs/security/multi_function_security/multi_function_security_appliance/sa_500/administration/guide/SA500_AG_OL1911404.pdf

Your external users type the public IP address into their browser, followed by the iTunes port. 

[WTIJ]

I am still lost.

The example on page 30 shows the generic/default ip address.  What IP do I change this do?  Does it matter?  How do I find an IP address that isn't already used?

I am brand new to this and honestly have no idea what I am doing.

I have access to the server and I know the IP address of the radio computer and it is currently running.  I am can access the stream inside the network, but I try to access it outside and get nothing.

[Georg Pauwen]

Hello,

when you access the audio stream from the inside, what do you type into your browser ? And what do you type from the outside ? I am just trying to get an idea of the addressing that is used now. By the way, when you say your users want to access the stream from the outside, does that mean from the Internet ?

[WTIJ]

Thanks for the continued help.

When I am within the network I use iTunes and open a stream of the host computer's IP address plus the port.  

From the outside I try to use the same IP address, but get nothing.  I try using the server IP and nothing.  I try combining them and nothing.

Within the network is fine, but from within the building we can just turn on the radio. I need access to the radio/audio stream from outside the network so people who are out of range of our tower or who have fuzzy reception can access what we play.

[Georg Pauwen]

What is the outside ? The public Internet ? Or just another part of the building ? What are the IP addresses of the users that are trying to connect from the outside, and what is the IP address of the server ? There needs to be a link between both and the iTunes port opened...

[WTIJ]

The outside is everything that is not our network.  I try to access the stream from home and am unable.

I only know the IP address of my computer and do not have other IP addresses.  I have yet to make it public knowledge that we have a stream.  Once I am able to get it up and running, then the general public will be made aware of how to access it.

[Georg Pauwen]

Hello,

sorry for the delay. Here is the thing:can you access the Internet from the network where the audio streaming server is running ? If that is the case, you already have a public IP address. That is the first thing to find out. So, can de radio ministry access websites on the Internet ?

[WTIJ]

I am able to access the internet from the office (within the network).  I know the IP address of the radio computer, otherwise connecting via iTunes would be impossible.

I know the IP address of the radio computer and the IP address of our modem and server (which is the same).  From within the network, the server also has another IP address.

What I don't know and don't understand is how to access the stream from outside the network.

Unless I've missed something I followed the document you provided, but still am unable to access the stream.

Modem IP Address is 64.85.184.7

Radio Computer's IP Address is 192.168.10.168

The port is set as 8011.

From within the network I am able to open iTunes and open a stream of 192.168.10.168:8011 and what is broadcast over the air plays over the internet/network.

How do I access this stream outside the network?

Thanks!
