The routing table looks OK to me.

The uplink cable plugs into a switch, load balancer plugs into the switch.
real_server plugs into ethernet device on the load balancer. The delay
happened when the uplink went straight into the load balancer as well. So
from the network stand point, seems pretty straight forward.

No, keepalived takes it out of the pool. I suppose I cound try taking it
out of the config entirely. Doubt it would have an effect though.

Thanks for the help by the way.
