Intranet WebRTC

[Don Park]

Looking at WebRTC source code, I don't see PeerConnection
configuration for direct connection which would be the case when all
clients are in the same Intranet.

Are we required to use a STUN server even when there isn't a firewall
to punch-through?

BTW, could someone confirm definitely that Chrome Canary
implementation of WebRTC as it stands currently *cannot* create
PeerConnections between two clients with same external IP address? If
so, whether this will be remedied eventually or not?

Best,

Don Park

No, a STUN server is not required when there is no NAT.

No, this should work, I don't know why this would be a problem.

Great. What should be passed as configuration? NULL or empty string?

Just realized one of the Macs I was testing with had firewall on.

Allowing incoming connection to Chrome Canary made the demos work.

Awesome! Thanks.

For now, empty string should suffice. However, this stuff is all getting reworked to handle things like different STUN/TURN servers, credentials, etc, so you'll want to keep an eye on this as it develops.

STUN/TURN is not required for vanilla networking cases.

Is a STUN/TURN server now required given that the API has changed since last March? I can't seem to find a conclusive answer on the Internet.

I want to set this up in an Intranet scenario for demonstration purposes and I'm not sure if I need to rely on an internal STUN server or not (our lab will be segmented from the Internet).

Host machines will be on the same subnet on the network, so there isn't going to be any NAT involved.

Paul,

Do you mean without ICE or without STUN?  ICE is required but if you are on the same subnet, STUN isn't required and you can just not configure a STUN server.

Very early webrtc days for me - but I am interested in the "intranet" use case - from what I see of the API's (in chrome) it does not seem possible to create a peer connection without ICE - what have I missed - if I do just pass a NULL string to the array - what "candidates" do I get ?

Please excuse if this a sumb newbiw question - I am now 3 days into my webrtc journey.

Exactly - the benefit of +sleep means I realise I should not post when tired,

Yes - I am running on an intranet, no nat and no requirement (or desire) for STUN or TURN. I was chasing how to "not" provide a STUN server. Do I just specify an empty string or should it be something like "stun:" with no name or ip address.
