A IIS server is located on 172.16.16.11 thats host a website on port 80
My Nginx-server is located on 192.168.1.49. (CentOS 7)
The DNS server points to the 192.168.1.49 machine with the A record of www.test.com and test.com that should proxy to 172.16.16.11.

Can someone help me a very basic config? Just want a quick and dirty configuration. Been following some tutorials on the web, even the most basic tuts seems to be to complicated for me. ;-)

Im running this at the moment in my nginx.conf. Only those lines, do I need rest of the config to?

server {
listen 80;
location / {
proxy_pass http://172.16.16.11;
}
}

My whole nginx.conf looks like this:

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
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 65;

#gzip on;

# include /etc/nginx/conf.d/*.conf;
#}

server {
listen 80;
server_name www.test.com;

access_log /var/log/nginx/access.log;


location / {
proxy_pass http://172.16.16.11/;
include /etc/nginx/proxy.conf;
}
}

If it works then leave it as it is, adding tuning parameters is always helpful but without knowing what to tune it makes no sense to add them all.

Query the users and check the logfiles to see if anything is misbehaving.

I got it to work. Hmm, seems I had to use the /etc/nginx/conf.d/default.conf file to add it into.
