nginx - Can't access docker over the internet -

i m going crazy trying docker accessible on internet. have created geoserver container on ubuntu 14.04 server using:

sudo docker run -d -p 80:8080 -t eliotjordan/docker-geoserver 

but when try connect server through web browser connection times out. know server accessible through domain name because running web site on it, using nginx web server stopped try this.

docker ps confirms running:

$ sudo docker ps container id        image                                 command                created             status              ports                  names 0e339661c232        eliotjordan/docker-geoserver:latest   "/bin/sh -c /opt/tom   4 seconds ago       4 seconds        0.0.0.0:80->8080/tcp   sad_morse 

and netstat shows port open:

i notice showing open on ipv6, problem? ufw disabled , can't think of else check.

i tried proxying through nginx had same result. reference here configuration used:

upstream geoserver_server {     server 127.0.0.1:80;  # tried 0.0.0.0:80 }  server {     listen 80;     server_name mydomain.com;      client_max_body_size 4g;      location / {         proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;         proxy_set_header x-forwarded-proto https;         proxy_set_header host $http_host;         proxy_pass http://geoserver_server;     } } 

update

here iptables configuration:

telnet connects locally, not external. ditto curl.

it should not problem see ipv6, server listening ipv4 request too. run netstat , ifconfig in container , post results?
