2. Click the «Settings» button.
3. Then go to the «Routing Settings» tab.
4. Make sure the «Enable Advanced Features» option is turned off.
5. In the «Direct Domain or IP» tab in the left column, enter the list of sites you want to exclude from the VPN. The list should look like this:
domain:yourdomain1, domain:yourdomain2, and so on For example: domain:blancvpn.com, domain:netflix.com,
6. Save the changes by clicking the «Confirm» button.
Done! Now, the sites you specified will not be accessed through VPN when the V2RayN client is on.
