disabling IPv6 for ICE #36

Closed 459below closed 9 years ago

459below commented 9 years ago

Although it'll be a few years until we will have full IPv6 connectivity, Recent Android Versions are very eager to use IPv6 anywhere they can. This seems to be a major problem in getting a proper peer-to-peer connection going to an IPv4 contact. Rooted devices can use echo "1" > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6 to temporary disable it. But I am very certain that most of the people do not have IPv6 connectivity and it should become a bigger problem the more people will get it, before it will become less of an issue again.

In ice4j, it's easy enough to simply ignore the candidates which contain the xxxx:xxxx:* pattern; that's what I did in my app.

Another thing to try is to pass the googIPv6:false option in your peer connection.

Thanks for the pointers. I'm not yet familiar with ICE or WebRTC, but I will try to find the appropriate lines to set this.

@459below setting this property will disable ipv6 in ice4j (the ICE library used in jitsi-android): org.ice4j.ipv6.DISABLED=true

@bgrozev Is there a wiki page or doc somewhere that lists the system props available for the jitsi projects? Especially in this case ice4j?

bgrozev commented 9 years ago

Unfortunately not.
