NOTE: One other solution that’s much easier is to NOT make OpenVPN the default gateway, then use the policy based routing field of the OpenVPN client to identify those IPs that should use the VPN. Of course, this is itself becomes a hassle if most of your IPs should be forced over the VPN. But it does work and only requires the GUI.
eibgrad - Sorry I have been away this week. Looking at the last note you made, how specifically would I go about this? Lets assume 18 IP Addresses 192.168.0.3 to 192.168.0.20 with 192.168.0.20 being the one device I don't want forced back over the vpn?
