How to determine the real IP of the visitor in htaccess?

Question

htaccess

Due to constant attempts to put the site, anti-ddos protection is connected. Traffic to the site comes through a proxy. When you try to register a ban or redirect for some users by IP in htaccess, nothing works, because instead of the real IP of the user, an IP proxy is determined. What can be written in htaccess so that the real IP is determined and the prescribed redirect rules work?
