NginX Proxy Manager behind XG

Question

Hello. 
 Scenerio: [XGHOME]------->[Docker_Revproxy]-----[SynologyNAS] 
 Is it possible to pass origin client IP to reverse proxy? Because Revproxy can see only gateway of Sophos XG. 
 Request on rev proxy look like this: 
 
 [13/Dec/2022:13:11:20 +0000] - 200 200 - POST https domain.example.com "/webapi/query.cgi" [ Client 10.192.168.1 ] [Length 78369] [Gzip -] [ Sent-to 10.192.168.2 ] "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36" "https domain.example.com /"

I don't recommend you to use both of them, either use WAF or Nginx. 
 If you're still going to use both of them, you try to look if Nginx-Proxy-Manager have the "ngx_http_realip_module", if it does you can use the "real_ip_header" to acquire the actual IPv4 address from the HTTP headers. 
 You can find more information about this on the Nginx Docs.
