Comodo Dome Firewall Appliance Web Console Issue

I have downloaded the ova appliance (Red Hat based) for the Dome Firewall after obtaining a 1-year free use license for the product. My problem is that when I installed the appliance in Oracle Virtual Box and clicked the box to reset the MAC addresses on all NICs, the Red Hat VM fires up and comes to a login screen. If I then go out on my Firefox web browser in Windows 10 Pro, which is the host PC for the VM, and type in https://192.168.0.15:10443 , the Dome Login screen never appears and my browser says that the connection timed out. I have no Internet connection issues and I cannot ping the 192.168.0.15 address since my network LAN is on a 192.168.1.0/24 network.

What am I doing wrong here? Please help.
