Ready so say “hello world” proper? In order to access your DIY NAS or home server or game server or whatever that is hosted at your house, you will need to do something called “port forwarding”. Port forwarding is usually performed and set up at the router level. Since there are hundreds and thousands of routers, I will be recommending you a few sites that you can take reference from. I will be using a popular custom router firmware (DDWRT) to illustrate the different steps that you will need to take in order to forward your ports correctly.
