Just use any multicast address you like - provided multicast is enabled you're good to go. > Also, I need to at least restrict the multicast broadcasts to a specific > network interface, is this possible? Its up to clients to subscribe to the multicast address; if they don't subscribe, they won't get the messages. But multicast goes everywhere - you can't limit it to specific network cards. -- James ------- http://macstrac.blogspot.com/ Open Source Integration http://open.iona.com
