Virtual network security configuration

Posted on April 28, 2015June 4, 2015 by coder

Only local access VM network creating

ALL OF the interfaces, `ROUTED` not `NAT`

no internet only routed net.

NAT is unsecure network, because server can reachable from internet.

So the best one is the NOT _ NAT

To create a similar batch file, you should verify the full paths to any directories that you want to

add to your system PATH variable. Then you can make any necessary changes to this
example code, and save it as a batch file on your system.
You can download a copy of my batch file using this URL:
