 * Since I installed Ninja Firewall (I love it, blocked a huge number of attacks!)–
   the payment gateway can not send back the answer of the succesful card payments.
   Where can I add an exeption IP address?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fipn-answer-blocked%2F%3Foutput_format%3Dmd&locale=en_US)

 * You can whitelist an IP address with the [.htninja configuration file](https://blog.nintechnet.com/ninjafirewall-wp-edition-the-htninja-configuration-file/).
   See the “ALLOW / BLOCK” section in the post.
   Alternatively, you can look in the
   firewall log for the blocked request, which will show the reason why it was blocked.
