I'm playing with LVS to try and get a working test setup going, and
I'm running into some problems.  I've got three VMs -- two "real"
servers, one LVS router.  Everything appears to start up correctly,
'ipvsadm -L' looks like I think it should, but the routing from the
VIP to the real servers just plain isn't happening.  Network
connectivity between the router and real servers works fine, but I
can't even connect to the VIP on port 80.

Following Redhat's documentation, I've tried both the iptables
PREROUTING and the arptables methods, but neither has worked.

I'm sure I've made a silly mistake, but I can't for the life of me
figure it out.  And LVS's logging is so quiet that I'm not getting
much; all appears to be working according to the logs.

Thanks for your help!
