Broadcasts only propagate to the local (broadcast) link, and are not routed (in particular, they are not routed across a PPP point-to-point link). So what you want to do is not "normal" for IP. I belive there should be a sysctl however that enables forwarding of broadcast packets received on a broadcast link over any point-to-point links that have a remote IP address matching the broadcast link's subnet (e.g., proxy-ARP'd remote clients). This would be "gross" but would also probably solve whatever problem you're trying to address. BTW, if you are trying to get Windows browsing to work, a better answer is to set up a WINS server (e.g., Samba or NT) and let your PPTP clients know about it via the "set ipcp nbns ..." command. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
