Setting NGINX to listen to a specific IP address

I have 2 external IP addresses on the VM that I’m running my production environment on. I have used the procedure outlined in the Corteza documentation to install NGINX and Corteza on the server, and set the .env file to one of the external IPs, but I want to host a separate instance of NGINX that will serve up web pages when requests come in to the other external IP address (port 80 and 443).

My questions:

  1. Will there be a problem running 2 NGINX containers if each is listening to a separate IP address?

  2. What do I need to do to get the currently installed NGINX (my-proxy) to listen to a particular IP address?
