Hi Jhonny I checked your architecture and zenlb configuration and all is
fine.
Is this architecture the best?. We would discuss with a lot of mail about
this idea, but I can tell you that like "best practices": Zen at the moment
works like sNAT method, for this is recommended that the virtual IP (zenlb
ip) and backends are on the same subnet. but I repeat it is the best
practice.
Maybe your architecture would the best selection on NAT or DR Load
balancing method, but quiet! Zen LB doesn't know this methods, at the
moment ;)
See you!
