Reverse Proxy

If you want to use a subdomain for the ZNC-Webinterface, you have to create a Reverse Proxy with your webserver.
Without setting TrustedProxy in your config you will only see 127.0.0.1 or ::1 for each web-access in your logs => You can't block specific IP's
If you want to see the real IP's you have to add this to your config:

TrustedProxy = 127.0.0.1
TrustedProxy = ::1

Nginx

server {
    listen 80;
    listen [::]:80;
    server_name znc.domain.tld;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://[::1]:6667/;
    }
}

Apache
