Hello, Here you can find simple IPv6 Multicasting application for windows: http://cboard.cprogramming.com/archive/index.php/t-67469.html It works locally but it does not work on my custom windows network. In my custom network IPv6 works just great - I can ping, connect, use forward and reverse DNS and etc., but this application does not work. Could you help me identify where is problem: * Does Microsoft windows support IPV6 multicasting? Should I enable it somewhere. I have disabled firewall completely but that does not help. * Are there any errors in that IPv6 multicasting example? It looks there is no mistake as far as I understand about IPv6 multicasting. * Have I missed anything? Best regards, Dalius
