Configuring Windows Defender Firewall on Windows 7

By default, Windows Defender Firewall blocks inbound connections, preventing Corellium devices from establishing a connection to a VPN-connected Windows computer. This prevents proxies, like Burp, from working, because the VM instance must be configured to proxy its traffic through the VPN-connected Windows computer.

To add a Firewall rule to allow network traffic originating from Corellium, on Windows 7, follow these instructions:
