Thanks! For the list archive: apply-candidate-acl is the sofia param to change the ACL from wan.auto to whatever. On 14.09.2015 20:36, Michael Jerris wrote:
The acl is totally configurable, the defaults for the candidates does not include these as the typical deployment (such as a server on he public internet) would not want those, but you of course can substitute your own acl based on your needs.

Uh, if I diagnosed this correctly, the local subnet fails the candidate checks, because it's not part of the wan.auto list. Can this be a configuration thing? Or is there a reason to disallow RTP traffic on the LAN?

Hello list,
testing some things on a LAN, I noticed Chrome and FS having problems establishing a direct LAN connection. Without any ICE servers and the SDP being limited to the host address, FS rejects what looks like a perfectly fine SDP with a codec negotiation error.
When TURN servers are available, Chrome already puts a TURN server's IP into the c= line. Other than that, there are just additional relay ice candidates. FS will choose the TURN server in the c= line first, but later "auto change" to the LAN address.
I could not find any other differences between the two SDPs. I've added some delay and checked listening ports to make sure this isn't a timing issue on Chrome's end: It does listen on the ports it announced ...
Is there a configuration option, which could cause this? I can't quite believe this being a bug, because a lot of people should have noticed ...
Thanks,
Thomas
P.S.:
