Heartbeat typically brings up the virtual IP when it starts a service
that uses it, and brings down the virtual IP after it stops a service.
It sounds like the two heartbeats are having one or more of the
following potential problems:
1) can't talk to each other (split brain) so both think the other is
dead, and both bring up IP's.
2) your interfaces are configured to start at boot time instead of being
controlled by heartbeat
3) some previous instance of heartbeat didn't shut down virtual
interfaces properly (but it sounds like you've rebooted since then).
If you're trying to run the same virtual IP on two different machines at
the same time, it won't work, you'll see what you're seeing now.

What is the mac address for the ip's in question at the router/firewall?
Which physical machine does that correspond to?
Post your heartbeat config and your ldirector config for both machines
(ideally, they are identical between the two machines). Also, make sure
that each machine can resolve and speak to each other. Also, which
version of heartbeat and which version of ldirector would be helpful.
