nginx not reachable from outside with SELINUX disabled - nginx

Question

I've just installed a CentOS 6.5 server and I've installed on it nginx.
I've disabled SELINUX and restarted the server but nginx is still not reachable from other servers except for the host itself.
This is my nginx configuration:
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes 4;
error_log /var/log/nginx/error.log;
#error_log /var/log/nginx/error.log notice;
#error_log /var/log/nginx/error.log info;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
# Load config files from the /etc/nginx/conf.d directory
# The default server is in conf.d/default.conf
include /etc/nginx/conf.d/*.conf;
}
What am I doing wrong?

Solved, there was a rule in IPTABLES that was blocking all incoming connections.
iptables -L INPUT -n --line-numbers
iptables -D INPUT <N>
service iptables save
service iptables restart
has solved the problem.
