Hi,
I need to stream audio/video using a 3G key.
Because 3G key is a connection with nat & proxy no public address, I need to send the stream to a webserver wich will stream the audio/video to Internnet.

So do you know if it is possible to do that :

[Laptop] =====3G usb key======> Streaming webserver <===broadband==== Client(s)

I think the laptop must send the stream throught proxy/nat because the webserver cannot access to the laptop and to save bandwith.


Best regards,

Yes.

"multicast Tunnel - mTunnel

--------------------------------------------------------------------------------
The mTunnel is an application that tunnels multicast packets over an unicast UDP channel. Several multicast streams can be sent over the same tunnel while the tunnel will still only use one port. This is useful if tunneling through a firewall.

The applications primary goal is to allow for easy tunneling of multicast over for instance a modem and/or an ISDN connection.

The mTunnel has a built in Web-server allowing for easy access to information about current tunnels.

This server listens by default on port 9000 on the machine where started.

The mTunnel also listens on session announcements for easier tunneling of known sessions.

If you download and install this package please send me an email! (peppar@cdt.luth.se)

The latest public version is 0.3 released 980102.

Download: Windows UNIX

This version is NOT compatible with earlier versions of mTunnel!

I have also written two papers about this application: Paper1 - 1998 Paper2 - 1997

run two Mtunnels, one on the laptop, one on the remote server....

multicast your video through the tunnel bypassing the 3G NAT,and have VLC at the other end pick it up and transcode to unicast as per usual.....on whatever port you like.

it would be nice to see if you manage it, and perhaps write up your step by step of how you did it....
