[KLUG Members] multicast

[Rusty Yonkers]

I have a system with 4 network segments that are connected with a
single Linux firewall system... I need to get multicast info from one
side of the system to the others.... I have done some research ... it
seems like if the kernel is setup to support it (not sure if the
stock SuSE 8.2 kernel is) then I might only have to put in a static
route.  I read an article that stated that I simply needed to also
put in ....
....................... section below from article ........

So far, so good. We've enabled multicasting. Now, we have to tell the
Linux kernel to actually do something with it, so we can start
routing. This means adding the Multicast virtual network to the
router table:

ip route add 224.0.0.0/4 dev eth0

(Assuming, of course, that you're multicasting over eth0! Substitute
the device of your choice, for this.)

Now, tell Linux to forward packets...

echo 1 > /proc/sys/net/ipv4/ip_forward

....................... end article section .............

I have ip forwarding turned on.  I am using iptables to perform
firewalling and nat'ing to the one side that ultimately goes to the
Internet....   I think I just need to add the ip route command.  Not
sure which device to use though... the one that has the multicast
server on it???
