I haven't worked with multicast much, but from my understanding you may have to join the router to the multicast domain.

The packets are addressed to 225.0.0.41 and static routes for that prefix are defined in both rc.conf files (I only use 1 multicast address, so I don't see a reason to use a multicast routing daemon). Obviously, I don't believe the static route is defined correctly. > > Can somebody clue me in to the proper method for configuring a FreeBSD computer, functioning as a network router, to accept all packets addressed to 225.0.0.41 on either Ethernet interface and forward them out the other??

It may be significant that when I installed the OS on the computer, there was only 1 NIC present. I added the other one after I got the software running, so it occurs to me that there may be a switch relating to forwarding that's not "ON", but I have no idea where to look for that. > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > -- -- Perfection is just a word I use occasionally with mustard. --Atom Powers--
