I when I said the configuration should be the same, I wasn't talking 
about the homogeneity of the the hardware.  I was trying to point at 
the Apache configurations.  The Apache configurations should be almost 
identical.  mod_backhand is a peer-based system; any system that 
receives a request from the client can choose (via rules to specify) to 
proxy that request to a peer machine for service.   The fact that you 
have decided to only put one machine in a position to field 
client-originating requests doesn't matter too much to backhand... It 
just means that one machine will receive the requests and (perhaps) 
forward those on to one of the other two peer instances.  If the 
removeSelf candidacy function was used, then the front machine would 
always pass the request along to one of its peers.

That's a good question, why is it 127.0.0.1?  The machine thinks it is 
called "enterprise".  Try logging onto that machine and typing:
ping enterprise

Does it ping 127.0.0.1?  If so, that's the machine's IP address. (hint: 
your /etc/hosts is likely not correct).

If for one reason or another you can't get it to resolve the IP address 
you want, then you can use the two parameter variant of the 
MulticastStats directive to explicitly announce the IP address you 
desire from each machine.
