Provide 2GB memory and click Next

Select the physical network for the management network for this router and click Next

Browse and select the VHD/VHD downloaded disk by using Use and existing Disk option and click Next

Review and click Finish to create the VM

Once the VM is create make sure to configure static MAC address and this will help In case you move a VLM system to a different Virtual Machine, ensure that the MAC addresses of the Virtual Machine’s NICs stay the same. Static MAC addresses must be configured for all NICs within Virtual Machines.

Edit the virtual machine settings to configure static MAC address

Power on the VM and it will boot from the hard disk which we downloaded. You can see below screen once booting complete.

If you configured DHCP you can use provided URL in the console to access the Web UI or you can login with default credentials provided in console to change IP. Login and it will automatically prompt below screen to change IP Address and Subnet Mask.
