streaming music on different subnet

Question

streaming music on different subnet

I've got a fairly basic network setup. I'm using adsl with a cisco 837 router. My isp has assigned me 16 static ip addresses. I've got a local dhcp server which hands out a range of ip's that have been provisioned to me via my isp which are used for workstations (laptops, desktops, et al), with the remaining staticly assigned (servers for example).

diagram;
telco=] 837/router -> switch -> devices

Everything is connected directly to the switch, except for wireless clients.

Now, to keep myself from running out of the 16 assigned ip addresses, I've setup a seperate subnet for devices which won't need contact with the internet world.

Those devices I've put under 10.1.0.0 of which I've given my airport express a 10.1.0.0 address.

Under iTunes on my iMac the airport express is listed in the drop-down box, when I select it, it sits forever stating it's connecting to the airport express.

On the other hand iTunes running on my laptop running windows does not present the drop-down box.

Is there any way to correct this, without having to give the airport express a public (non 10.x.x.x) ip address?

G5 iMac, Mac OS X (10.4.5)

You have given the AE an IP address for a network, not a device on that network based on a standard subnet mask. Each network has two unassignable numbers, the IP address of the network, and broadcast. Try 10.1.0.1 for your AE. If you want devices on different subnets to have access, they need to at least be on the same network, and then alter the subnet mask for them so both subnets appear on the same network. Devices assigned with the public network IPs will be difficult to configure, so they see the private non-routable network, but I think it can be done???? I would try another scheme.... give the AE one of the static IPs and then NAT with it. Then it would be a Gateway to the computers behind it for the others in your public range.... but that's just me . Hope that helps.

You have given the AE an IP address for a network,
not a device on that network based on a standard
subnet mask. Each network has two unassignable
numbers, the IP address of the network, and
broadcast. Try 10.1.0.1 for your AE.

I was just giving an example of the network configuration, the ip address of the AE is not actually 10.1.0.0 but 10.1.0.4.

If you want
devices on different subnets to have access, they
need to at least be on the same network, and then
alter the subnet mask for them so both subnets appear
on the same network.

They are on the same network, in the sense that I can talk to a 10.1.0.x address from one of my public ip addresses and vice versa. The only difference is 10.1.0.x cannot talk to anything wan side where machines/devices with a public address can.

Devices assigned with the
public network IPs will be difficult to configure, so
they see the private non-routable network, but I
think it can be done???? I would try another
scheme.... give the AE one of the static IPs and then
NAT with it. Then it would be a Gateway to the
computers behind it for the others in your public
range.... but that's just me . Hope that helps.

I am not looking to setting up NAT. I already have a gateway, the cisco 837 router. I already have a wireless access point which I recently mounted. Thus, I'm not needing any of the wifi capabilities of the AE, but just the airtunes facilities to local machines running on my lan.

Just to reclarify, I have an ip range in the 217.155.6.x block, and to keep myself from using all of the ips in that block, I'm using 10.1.x.x addresses (non-traversable) for the remaining bits that don't require wan side communication.

I took my own advice and RTFM. The AE setup guide "implies" but does not distinctly state that the Itunes devices have to be wireless and "you may have to join the network" in order to stream music to the AE. What I get from that is that any of them can stream music from their Itunes to the stereo jack on the AE, in fact they can send to any AE in its network as long as it's only one at a time. So, I guess that would allow them to take turns sending their music to the office stereo. As long as they were members of the AE wireless network......

I would do it the other way around, do Podcasts and let each person decide what flavor they wish to sign up for to play on their own machines.

If all of those computers are members of the AE wireless network and you are trying to send music to a stereo attached to the AE, I don't have a clue as to why it won't work. If I actually had one to play with, I probably could figure it out....... instead of interpolating the IP addresses you posted as being ..... and replying....

Somewhat related question. Have been trying to do this: Can get on the internet with a wireless hospital network using my Powerbook G4. I would like to stream music from my Powerbook G4 to an Airport Express hooked up to an Operating Room Stereo. Have tried all types of set-ups but it doesn't work. Any ideas?

iTunes prohibits streaming music except for devices on the local network. You have two different subnets, streaming is not allowed.

this is local, just a different set of ips for internal use only nodes.

Having two subnets on the same physical network is no different than if they were on separate physical networks as far as the protocols are concerned. If the Express and the computers are not in the same IP subnet, AirTunes will not work. Part (most?) of the reason for this is that Bonjour is required for AirTunes and Bonjour only works on the local subnet.
