How to Set Up a Virtual Switch to Enable NAT to Domains (Oracle Solaris 11)

Create an Oracle Solaris 11 etherstub device.
```
primary# dladm create-etherstub stub0
```
Create a virtual switch that uses stub0 as the physical back-end device.
```
primary# ldm add-vsw net-dev=stub0 primary-stub-vsw0 primary
```

Create a VNIC on the stub0 device.

primary# dladm create-vnic -l stub0 vnic0

Configure vnic0 as the network interface.

primary# ipadm create-ip vnic0
primary# ipadm create-addr -T static -a 192.168.100.1/24  vnic0/v4static

Enable IPv4 forwarding and create NAT rules to provide external connectivity to the domains.
