 * Hi [@kora3848](https://wordpress.org/support/users/kora3848/), thanks for your
   question.
 * When using Cloudflare with an origin server that has a dynamic IP, I am not aware
   of a suitable option to pick that has the same result as adding the IP as per
   our instructions. If you know which range of IPs your site may be assigned, you
   could allow that range past Cloudflare using “**IP Access Rules**“, but that 
   would allow any other hosts in that range past Cloudflare too. It could be worth
   checking in with Cloudflare or hosting support if they provide Cloudflare on 
   your behalf.
 * If you can’t see “Allow”, our instructions seem to still match Cloudflare’s terminology
   so check you aren’t mixing up “Custom Rules” and “IP Access Rules”: [https://www.wordfence.com/help/advanced/compatibility/](https://www.wordfence.com/help/advanced/compatibility/)
 * Thanks,
   Peter.
