Forwarding port 80 requests using reverse proxy

Hello all,

I am not very technologically savvy in the networking realm and I apologize if I fall behind on certain terminology ahead of time.
I have a dynamic dns domain through noip.com, which I will reference as domain.example. I also have a public IP address which I will reference as 68.***.***.***.

The dynamic dns domain (domain.example) is assigned to my public IP address (68.***.***.***). I have an AirPort Extreme that I can open ports on and I have it configured as such: http://imgur.com/a/Ig0Ay.

Basically what I am trying to do is when someone accesses domain.example, I want nginx to forward them to domain.example:3001. Currently I am able to open port 80 on my router and I can navigate to domain.example with my LAN, but as soon as I travel outside of my house, it doesn't work... I know that my ISP blocks 80 for residential accounts and this is why I am attempting to setup this domain forwarding. Please any help would be greatly appreciated!




This is my current nginx configuration:



#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
worker_connections 1024;
}


http {
include mime.types;
default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;

server {
