Hello, I'm posting it here because I'm not sure if this is a bug. I have a network connected to the net through my FreeBSD box, using user-level PPP with aliasing enabled. I wanted to do some MBONE tests with a friend (not connected to MBONE, we simply set up a mrouted tunnel between us). So, in the same box with the ppp in aliasing mode, I started mrouted with a tunnel to my friend's machine. He received my igmp messages, and (verifying it with tcpdump) he was sending them to me, but I idn't receive them. After a lot of tests, including setting up a ppp-over-tcp link between our machines, as I thought that some machine between us was filtering the igmp datagrams, I found that the igmp was failing because I had aliasing enabled in PPP. (It was failing also in the ppp-over-tcp link). Is this normal? I guess ppp should be transparent to messages originated at the same machine where the ppp daemon is running. The curious thing is that he received my igmp messages, but I didn't receive his messages! Thanks, Borja. -- *********************************************************************** Borja Marcos * Internet: borjam@we.lc.ehu.es Alangoeta, 11 1 izq * borjam@well.com 48990 - Algorta (Vizcaya) * borjamar@sarenet.es SPAIN * CompuServe: 100015,3502 ***********************************************************************
