Nighthawk Rax30 OPENVPN Public IP on MAC

I setup an OpenVPN Server on RAX 30.

The Box is checked = All sites on the Internet and Home Network.

On Windwos client the vpn tunnel becomes public ip from Nighthawk everything good.

But not on Mac i can only reach my LAN but Public IP is not from Nighthawk.

Tested VPN Clients on Mac are:

Tunnelblick with option "route all trafic through vpn"

Open VPN Client with redirect-gateway on config file.

Both methods are not working.

What ist the solution?

Best regards
