SSTP Split Tunnel problem

Hi,

I have successfully installed a MT CHR as an SSTP Server with Windows 10 Clients. But when it comes to Split Tunneling I am stuck at the moment.

I know I can force the Windows 10 clients to use a Split Tunnel by manipulating the VPN Interface and having it not use the tunnel’s default gateway.

But this leeds to unreachable RFC1918 networks locally connected to the CHR.

Is there a way to tell the Windows 10 SSTP clients which networks are reachable via the tunnel?

Thanks!

Not sure if I am missing the purpose of the OP, but maybe ha,be a rad through these
