Hi! I have a wordpress page with Ubuntu and Nginx. I know .htaccess does not work with nginx for block IPs.

I try to deny one IP per exemple my mobile ip: 123.123.123.123 in IPTables unsuccessfully with this:

iptables -A INPUT -s 123.123.123.123 -j DROP
iptables -A OUTPUT -s 123.123.123.123 -j DROP
sudo /sbin/iptables-save
I can open my website

I also try with virtual servers in /etc/nginx/sites-available/mydomain.com

server {
listen 80;
root /var/www/html/myfolder;
index index.php index.html index.html
servername mydomain.com www.mydomain.com;
rewrite ^/sitemapindex.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemapn=$2 last;
location / {
deny 123.123.123.123;
tryfiles $uri $uri/ /index.php?q=$uri&$args;
}

then reload / restar Nginx and i also can open my website from my IP....

Is something wrong?
