For split-include to work on Windows 10, modify your VPN connection properties as follows:
- Select the VPN connection to modify, in the “Settings” applet and choose “Change adapter options” under “Related Settings”
- In the “Network Connections” window, right-click the VPN connection and choose “Properties”
- Choose the “Networking” tab and for each protocol (IPv6 and/or IPv4) you wish to configure:
a) Highlight the protocol and click “Properties”
b) Click “Advanced”
c) Uncheck “Use default gateway on remote network”
d) Check “Disable class based route addition”
Once all changes are done, that’s it. Now Windows respect RouterOS split-include configuration.
I have already sent this information to MikroTik support, so hopefully they will update the Wiki with the solution.
