+====== NAT ======
+When backing up configurations or doing filetransfers, the transfer is usually started from the node towards NetYCE.
+> Commands are send to the devices to do those kind of executions.
+Because of the initiation on the node, the node needs to be able to reach the NetYCE instance. In some circumstances the NetYCE instance is NAT-ted, therefore known to the node with a different IP address.
+Thus the NetYCE application needs to be configured to use this specific IP adress.
+{{guides:howto:how_to_go_around_nat_1_.png?nolink|}}
+Shown in the example above, the netYCE VM resides inside a Laptop/Desktop/server
+The IP address of the VM is 192.169.190.128 and Host (Desktop/Laptop IP/server) IP is 10.1.222.61
+Thus the setup of NetYCE on login is as below
+<code>
