> I'm a clueless newbie here :) Ya, the clients have to tunnel if their ISP doesn't support multicast. They can tunnel on their own, or use a router or firewall that'll do the tunneling for them. Of course, I don't know if Windows has support for tunneling on its own. I'm willing to bet that 95, 98, ME, and XP don't support tunneling, but do support direct multicast. While NT and 2000 support multicast, probably only the Advanced Servers, Servers, and suchlike support the tunneling piece. Though, knowing Microbloat, it's probably just a registry key that you tweak in order to support multicast tunneling. I've tried some searches on that blasted microsoft knowledge base, and the best information that I've been able to find is at: http://www.microsoft.com/windows2000/techinfo/planning/communications/mu lticaststeps.asp This doc talks about how to set up multicast conferencing in Win2k using TAPI and Phone Dialer. Its pretty useless for most peolpe (requires an active directory server on the local network), but at least it contains the following paragraph: CONFIGURING THE NETWORK BACKBONE TAPI IP multicast relies on the ability of the network backbone to carry IP multicast packets. Windows 2000 Professional-based workstations connected to a common Ethernet network can participate in multicast without additional network configuration. If a deployment scenario involves conference participants located on different networks, some router configuration might be required. I take this paragraph to mean that Windows 2000 Professional definately does not support multicast tunneling on its own, that it requires an external router to perform that function. I have not found any document that describes the "some router configuration". Well, that's not true. I've found lots of data on this for Cisco, Linux, Solaris, and others. But nothing for Windows type systems. So /if/ tunneling is supported under Windows, I have no clue what is required to activate it or configure it. My test environment has two windows boxen, and they're connected to a fully multicast-capable network with multicast routers and all that fun stuff. So they don't have to worry about multicast tunneling. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
