[Freeswitch-users] Web RTC -> No Candidate found

[Alexander Haugg]

Hi,

I have the problem, that the freeswitch don't accept the network internal candidate.

The local IP address of the fs is 192.168.241.5
The local IP address of the webrtc Client is 192.168.241.2

In the acl.conf.xml is set:
<list name="localnet.auto" default="allow">
                <node type="allow" cidr="192.168.241.0/24"/>
</list>

In the sofia profile is set:
<param name="local-network-acl" value="localnet.auto"/>
<param name="apply-inbound-acl" value="localnet.auto"/>

The following SDP is send by the client:
v=0
o=- 222075295642546336 815544600 IN IP4 127.0.0.1
