VPS with Multiple IP Question

Hi.

---

I have a BuyVM VPS with 2 IPs.

1 IP is Regular IP
1 IP is DDOS Protected IP.

I installed CentMinMod successfully.

I edited my domains vhost for it to listen on the DDOS Protected IP.

When I enter my regular IP in my browser it still connects to the webserver.

How can I make it so that the webserver only runs on the filtered IP.

I am only going to use my regular IP to ssh into the box.

Thanks

Edit: I did some research and came across this

configure nginx to listen on single ip address - WebHostingNeeds.com

It looks like what I am looking for.


But I'm not sure which nginx.conf to edit

I ran: "locate nginx.conf" on my server and found these.

/svr-setup/nginx-1.9.9/conf/nginx.conf
/usr/local/nginx/conf/nginx.conf
/usr/local/nginx/conf/nginx.conf.default
/usr/local/src/centminmod/config/nginx/nginx.conf

 

In
/usr/local/nginx/conf/nginx.conf
it does not say listen 80 anywhere.

should I just add listen myip:80 to the top of the file?
