A user was interested in getting a Multicast Tunnel running through user PPP on FreeBSD. The outgoing tunnel send IGMP packets out through the PPP code and is recieved on our network, but the incoming IGMP packets are not being logged (using tcpdump and the TCP/IP log facility in ppp). I modified the switch statement in PacketCheck() to log a IPPROTO_IGMP as a IPPROTO_UDP type, but I do not see the IGMP packets in the log. we don't have the most sophisticated debuging tools, but the terminal server seems to say that they are sending the incoming (to the ppp link) packet and it appears from the modem light the packet is getting on to the modem. Since I do not have a firewall defined FilterCheck() in ip.c should not be eliminating this packet. I swear we had a tunnel running on the user ppp code a couple months ago under FreeBSD 2.2.2. Has anyone else been using user ppp and an multicast tunnel? The only thing I can think of is this ppp session is using aliasing, but the IGMP packets are coming into the ppp machine and not going through it. --mark.
