The mrouted at the other end of the tunnel should detect the presence of groups, i.e. a router can only detect groups on any attached interface. I don't see why the path of the dump files should be changed to /var/tmp and /var/run. A number of systems do not have a directory called /var/run. >instead of changing the ip->ip_p in /sys/netinet/ip_mroute.c and in >/usr/src/usr.sbin/mrouted/igmp.c when adding the groups, I had tucked the >packet down the raw socket stored in ip_mrouter; this has the advantage of >not making all of the utilities (mrinfo, map-mbone, mtrace) that also >have raw sockets open to have to throw out the extra packet: Good point. Let me check the operation of this. Thanks for the help, Ajit
