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:
Instructions
- Open Windows Defender Firewall.
- Click Advanced Settings on the left-hand side.
- Click Inbound Rules on the left-hand side.
- Click New Rule... on the right-hand side. The New Inbound Rule Wizard will appear. Select the Custom radio button, then click Next.
- Select the All Programs radio button, then click Next.
- Click Next.
- Select These IP addresses for the first question, then click Add...
- Enter
10.11.3.0/22
, the VPN subnet. Then click OK.
- 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.
- Click Next.
- Select Allow the connection, then click Next.
- Check off Domain, Private, and Public. Then, click Next.
- Name the rule, then click Finish.
- 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.
