I guess the biggest confusion is that fact it doesn't specify you will need to add a static route to your other gateways so it knows to pass traffic destined for the isolated network to the LB. In a L4xNAT config, does the LB NAT only traffic requested externally or will it NAT all traffic from the real servers?
