Intel CS v4.1: Windows client does not support proxy servers

[Roland_B_]

Hi,

when using the ICS v4.1 Windows client conference sample I am NOT able to connect 
to a ICS server in the internet from behind a corporate firewall/proxy.

My setting:
---------------- 

• ICS v4.1 server on internet server (port 443)
• TURN server (coturn) on another internet server (TCP port 443)
• all secured with SSL certificates (only port 443 is used)
• corporate network with proxy server (without authentication)
• this setup works with the javascript client (chrome) without any problems (through corporate proxy)

But the ICS v4.1 Windows client can NOT to this internet server through the corporate firewall/proxy.
There is no way to configure a proxy server address in this client.

I have changed the "socket.io-cpp-client" to read the proxy server address from the environment variable (https_proxy).
The Intel Windows SDK uses this "socket.io-cpp-client" to communicate with the ICS server.
Now, the websocket communication works (ConferenceClient::Join() succeeds  /  getToken() works).

But the Intel Windows SDK can NOT publish the media stream through the proxy/TURN server.
Is there a way to set the proxy server address in the Intel Windows Client SDK (hidden variable, environment variable, ...)???
Any idea?

My ICE server setting in the Windows client:
---------------------------------------------------------------
 

IceServer ice1, ice2;
ice1.username = "";
ice1.password = "";
ice1.urls.push_back("stun:138.201.57.76:443");   // STUN server in the internet
ice2.username = "turn_username";
ice2.password = "turn_password";
ice2.urls.push_back("turn:138.201.57.76:443?transport=tcp");   // TURN server in the internet
std::vector<IceServer> ice_servers;
ice_servers.push_back(ice1);
ice_servers.push_back(ice2);
configuration_.ice_servers = ice_servers;
room = ConferenceClient::Create(configuration_);

I am getting STUN/TURN server connect errors:
---------------------------------------------------------------------

I have updated the logfile.

Has anyone tried to use the Windows SDK behind a corporate proxy?

Any ideas?
Thanks!

Our Windows SDK don't support proxy setting currently .
