1 Use the .htaccess file generator.
2 Enter your GoodAccess gateway's Static IP address and click Generate .htaccess File
3 Set I want to allow these IP addresses and ban everyone else.
4 Create .htaccess file with the generated content and copy it to your web server. Place it in the directory containing the part of the website which should be protected.
5 Test the access without GoodAccess to be sure access is not allowed to the public.
6 Congratulations! From now on your system will be protected and accessible only for your team via GoodAccess.
Note: In case the .htaccess file doesn't work, be sure you have your APACHE configured with directive AllowOverride All. See APACHE AllowOverride documentation.
