Based on your feedback we have released some awesome updates for HA-IP.
Most of the feedback that we received since launch was regarding the missing visitor IP address. In this update we have fixed this! In HTTP mode the visitor IP address is added as an additional header (X-Forwarded-For).
To make visitor IP forwarding also possible for HTTPS traffic, you will need to install a Let's Encrypt certificate on your HA-IP. You can now use our hassle-free service in the control panel to enable Let's Encrypt for your HA-IP.
