The NAT node will use the VMware vmnet adapter instead of the libvirt NAT feature of the GNS3 VM provided VMware is installed on Windows or MAC. This allows to connect a Dynamips topology to the Internet without having to boot a GNS3 VM. It’s usefull when you need to download stuff from internet (package, licence check…). And it’s easier to use than the Cloud node.
The NAT node require the GNS3 VM or a Linux computer with libvirt installed.
By default the NAT node run a DHCP server that will give you an ip in the range 192.168.122.0/24.
The result of test can not operate on IOU Switch but IOU Router can use this. |
