Re: Probably a simple question but...

Are you running mrouted?

I believe this is a simple fix, but I sure

I set up 2 FreeBSD boxes as dual-stack
network routers and I'm using them to test an
application capable of generating both TCP and
UDP messaging. The TCP part of this equation
is working great -- my message fly around the
network just like they should.

However, my routers appear to be eating my
multicast UDP packets. 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??
(they're RL0 and RL1, lower case.)

Do I need to define 2 static routes?
Do I need to switch something else on?



Thanks for any help,
Rich Mayo



P.S. 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.
