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:


Instructions

  1. Open Windows Defender Firewall.

  2. Click Advanced Settings on the left-hand side.

  3. Click Inbound Rules on the left-hand side.

  4. Click New Rule... on the right-hand side. The New Inbound Rule Wizard will appear. Select the Custom radio button, then click Next.

  5. Select the All Programs radio button, then click Next.

  6. Click Next.

  7. Select These IP addresses for the first question, then click Add...

  8. Enter 10.11.3.0/22, the VPN subnet. Then click OK.

  9. Select These IP addresses for the second question, then click Add.... Enter 10.11.0.0/15, the Corellium VM instance subnet, then click OK.

  10. Click Next.

  11. Select Allow the connection, then click Next.

  12. Check off Domain, Private, and Public. Then, click Next.

  13. Name the rule, then click Finish.

  14. You should see your rule in the Inbound Rules tab.

You should now be able to establish connections from a Corellium VM instance to your VPN-connected client.
