I am setting up Nginx servers behind the ELB. I set up so that api.app.com points to an ELB. I wonder which addresses I should use for remote connections, Nginx settings etc..

1) For example, in Nginx:

Should I do

 server {
          listen 80;
#What is the right line here:
#              server_name <WWW.NAME.COM> OR <ec2-.....compute-1.amazonaws.com> OR <MLB-....amazonaws.com>?;
         passenger_enabled on;

2) I connect servers behind ELB to remote Postgres database. In Postgres settings should I open the ELB address (MLB-...amazonws.com) or to individual EC2 IPs?

The server_name should be set to your web site's hostname, that people will actually type in.
