Might be unrelated to your issue, but we face problems when
- WAF is in front of an nginx, which is balancing our websites,
- WAF is configured in Transparent Reverse Proxy mode,
- and a technique like this is used on nginx to serve https://www.siteA.com/sitemap.xml as an alternative URL: https://www.siteB.com/sitemap/en/sitemap.xml
The sample nginx config is like this:
location = /sitemap.xml {
proxy_pass https://www.siteB.hu/sitemap/en/sitemap.xml;
}
Then WAF then simply cannot step in the HTTPS traffic, and blocking the access entirely to the site without any logs entries

Subject: Nginx LB Behind Imperva WAF
Has anyone seen any issues with deploying an Nginx load balancer behind Imperva Cloud WAF? We see intermittent issues when we do this, and have found no helpful log entries that point to a cause. Also cannot seem to find anyone else reporting a similar issue.
