To do this it suffices to duplicate the block of settings for each listener which has to listen for both protocols, and configure one listener of each resulting pair to listen for IPv6 and another one to listen for IPv4. This can be done either by using the "inet6" option of by specifying appropriate IP addresses as ejabberd is now able to figure out the necessary protocol from the format of an IP address assigned to the listener as described in [1]. So, to implement support for c2s connections using both IPv4 and IPv6 on all available interfaces, one would write in the config file: {listen, {{5222, "0.0.0.0"}, ejabberd_c2s, [...]}, {{5222, "::"}, ejabberd_c2s, [...]}, ... } with the first c2s listener supporting IPv4 and the second -- IPv6. If you have an access to a server with mixed IPv4/IPv6 connectivity, please test and report back. 1. http://www.process-one.net/en/ejabberd/guide_en#listened -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
