Hi, I have a tiny Linux PC (Mighty Mite) running as a router. I runs mrouted and has IP forwarding enabled in /proc. My problem is that I want to block TCP from being routed but still allow multicast routing via the mrouted. Cheap and dirty, can I disable the IP forwarding in /proc and still have multicast work via mrouted? Or is my only option to use ipchains? (Note that this is part of R&D in a lab so I'm not worried about the security aspect of ipchains.) Thanks, Tuan - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
