To complete my response: OS is Windows XP SP1 with installed ipv6 support using command "ipv6 install" what was succesfull.
Before ipv6 support was installed the server was running bind to ipv4 ip of type "any address" (0.0.0.0:portnum) and it was able to accept connections to ::1 ipv6 loopback address only. -hb- _______________________________________________ Mozilla-netlib mailing list Mozilla-netlib@mozilla.org http://mail.mozilla.org/listinfo/mozilla-netlib
