Poweroff the Virtual Machine. 2. Re-size the VM. 3. Resume the Virtual Machine using the new capacity. | | Resizing VM | If you have created a Virtual Machine and you need more resources, the following procedure is recommended: Perform any operation needed to prepare your Virtual Machine for shutting down, e.g. you may want to manually stop some services... 1.

 To use the redirects of TCP connections, you must add **TCP_PORT_FORWARDING** attribute value with the desired connections (max 4). After changing the attribute value, remember to restart your VM (PowerOff → Boot) and to check which connections were created. For example, if you want to open connection 80, type 80 and restart the VM. You will see TCP_PORT_FORWARDING value change to PORT: 80, where PORT is an external IP (PUBLIC_IP value) connection through which you can connect to the VM of your desired connection (80). To use the redirects of TCP connections, you must add **TCP_PORT_FORWARDING** attribute value with the desired connections (max 4).

 +=== Virtual machine network settings === 
 + 
 +From September 1, 2022, by default, the virtual machine can only be accessed from the MIF network and via VU VPN. To make your virtual machine accessible from external networks, you would need to change the firewall in the network settings in the template you will use to create the virtual machine. 
 + 
 +1. If you are building a machine using templates. Choose the template you want, open it and make a copy by pressing the Clone button. 
 + 
 +2. Open the copy of your template and press Update → Network → Advanced Options. 
 + 
 +3. Below you will find Security Groups, by default vu-vpn-mif will be selected, you need to select default and save the template.
