Hi,

right now I am using only one external server as a gateway for the internal servers.
I would like to enable a fail-over on a second server.
To implement the floating VIP, should I use heartbeat+pacemaker?
Or is there something more "lightweight"?
Basically, I just need server2 up the VIP when server1 is down, and server2 down the VIP when server1 is back up (or server 1 does not up the VIP seeing server2 has it already).

Thx,
JD
