I've been working on a Linux PPTP VPN server for clients that require multicasting. I only have one physical interface in the box and I'm using the PoPToP package for PPTP support. Getting the VPN setup and working hasn't been a problem, getting the multicast traffic to flow between the ppp and eth0 interface is causing me a whole lot of problems. What do I need to do so that I can tell the kernel to forward all relevant multicast traffic through to the clients (in essence just a simple IGMP router)? I've been looking at mrouted, pimd-dense and mrtd but haven't had any luck getting them to work because of the dynamic nature of the PPP interfaces. My backup is a W2K server which I've had some luck getting to work but I would really hate to use it unless I need to because there is a huge political battle raging right now about Linux being a sub standard OS.
