It's possible (just specify the ethernet device you want to communicate over in ha.cf), but, quite frankly, it's stupid to restrict Heartbeat comms to just one link. You always want your cluster nodes to communicate over at least two independent links, otherwise you're just signing up for split brain sooner or later. "man ha.cf" is probably helpful. An HTML version of that man page is also available here: http://www.linux-ha.org/doc/re-hacf.html Cheers, Florian
