Comment 11 for bug 1930200

From the use case in the RFE, it works more likely a attached fip which forward original external flows to a local port. And blocks traffic from outside. Use case and expected behavior should be:

Initial state：

NodeA： VM-A1(portA1) VM-A2(portA2)
NodeB： VM-B1(portB1) VM-B2(portB2)
NodeC： VM-C1(portC1)
NodeService: VM-Service(portService(10.10.10.10))

Expected behavior: All VMs A1,A2,B1,B2,C1 connect to portService(10.10.10.10) and fetch data.

After enable NLVIP, it works similar as fip and attach to local service VMs:

NodeA： VM-A1(portA1) VM-A2(portA2+NLVIPA1(10.10.10.10))
NodeB： VM-B1(portB1) VM-B2(portB2+NLVIPB1(10.10.10.10))
NodeC： VM-C1(portC1)
NodeService: VM-Service(portService(10.10.10.10))

Expected behavior:
VM-A1 connect to NLVIPA1 for local service with high performance. VM-A1 to portService(10.10.10.10) is blocked.
VM-B1 connect to NLVIPB1 for local service with high performance. VM-B1 to portService(10.10.10.10) is blocked.
VM-C1 connect to portService(10.10.10.10) as original with low performance.
