VirtualBox forward ports below 1024

The VirtualBox online-manual writes “Forwarding host ports < 1024 impossible…”. This tutorial shows that it is still possible. I know that there are several reasons not to do so, but there are also reasons where it is necessary.


  • VirtualBox with VM configured (not running)
  • You know the root password

Example for Ubuntu

Now you probably need to import the VM. Attention! The acces rights will be changed!

Port Forwarding

Configure or just check the port forwarding. To do so, you can use the graphical port forwarding editor or even the command line (VBoxManage).

At the end you can start the VM as root.
