OVH CDN

Hi,

Have a problem with inter-site integration. Namely, Hootsuite get 403 error publishing URL of my WP pages to Facebook.

The problem manifests in the Cerber activity log. I can see that all the traffic went from 51.254.41.x and 137.74.122.x, including my just made login to WP, but my IP is different. So Cerber incorrectly identifies IP of origin. First problem: it’s impossible to investigate nothing. Second: CDN server’s IP is blacklisted and Cerber blocks legitimate requests. I have Inverse Proxy setting activated. The hosting is OVH.es and OVH CDN active. I have installed iThemes Security plugin, it identifies IPs wrong also. But in its log I can see more details. It’s just example. The Real IP appears at REMOTE_ADDR and HTTP_REMOTE_IP fields.
