Is this last line enough to work linux as multicast router ? No, you need some kind of routing daemon for multicast forwarding/routing. Look for "mrouted" or "zebra". There is a HowTo for multicast, but no big infos on multicast forwarding/routing .... http://www.linuxjunkies.org/html/Multicast-HOWTO.html > There is also one alternative we found: XORP ( Open Source IP Router ) > http://www.xorp.org/livecd.html#getting > But this works from live cd.

But if it is a Linux based live cd i'm sure you, can also install it on disk :) > It is enough to use the linux as router, we do not consider the router > algorithms or any other thing. regards, Tami _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
