This is my first shot at making Varnish work on my dedicated server which hosts 2 domains with 2 separate IP-addresses. My simplified setup is as follows:

Nginx conf

server {
    listen ip-address-1:8080;
}

server {
    listen ip-address-2:8080;
}

Varnish vcl

backend default {
    .host = "127.0.0.1";
    .port = "80";
}

And in the varnish conf I have defined

VARNISH_LISTEN_PORT=80

Varnish and Nginx (and php-fpm) are running properly but when I try to go to my website it shows the welcome to nginx page. The headers don't have the x-varnish in it. It seems that for some reason varnish is not listening to port 80. I'm suspecting this has to do with the vcl file where it is listening to the 127.0.0.1 host. I'm running two wordpress sites. Where should I look for to get Varnish working properly?

Cheers, Adnan

EDIT:

Nginx seems to be in 8080 correctly but Varnish is not listening to the right ip address. Using Jens multiple varnish ip addresses netstat -lnp yields:
