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--
