It's a little harder with multicast, and mrouted doesn't support it (yet?). You need real subnets on each side. However, if the thing on the other end of the PPP link doesn't support DVMRP, then running natively on gw doesn't make sense anyway -- you can just disable the ppp interface and install a tunnel to whomever you're going to get a tunnel from. You might also have to use the "netmask" and "altnet" keywords on your ethernet interface to avoid advertising a DVMRP route for more than you're responsible for. Bill
