View Full Version : Port forwarding for NP3900

01-23-2012, 01:19 PM

I recently bought a NP3900: great sound.
Now I need to get it to work in a sub-network, essentially it is connected to a Zyxel Zywall (sub-network) which is connected to the main VDSL Modem. (I had to choose this solution in order to get my NAS to work with BluewinTV)

In order to get it to work I would need to know how to configure port forwarding on my Zywall.
Can someone please suggest me which port (or port range) I should set to be forwarded within my Zywall, please ?
Anything else I should do / configure ?

Thanks a lot in advance !

Would contact Zywall for this.

thanks for your suggestion.
I think that is not the point: I can handle the Zywall configuration (and I did it successfully with a bunch of other devices), but I have no idea about the port/port_range Philips is using to transfer the audio stream.
For this reason I would really appreciate if Philips or somebody else could answer my simple question.

Thank you

I found the answer myself.
Streamium is using the standard port 80, so that essentially you don't have to configure anything since this port is typically already open for Http protocol. So in a sub network if the data provided by the DHCP server are correct then everything should work smoothly.
In my case that port was closed for policy reasons so it didn't work.

That being said I consider sad not getting any answer or support whatsoever by Philips: great products should be coupled with good support.

Hi !

Port 80 is (or may) be used for the audio stream, but to get the UPnP framework to work, you need at least two more ports :
1900 UDP and 2869 TCP port must be opened up.

The problem is that you will not be able to forward the UPnP (UDP) broadcasts from one subnet to another, even if you can open up for UDP packets on UDB port 1900 between your subnets ;-(
(Perhaps some serious customized hacking in a DD-WRT router would allow this, but I am really not sure if even that is possible.)

Cheers !
