This is a problem that I’ve been trying to crack for a long time now. I want to be able to access my home network remotely. The problem seems simple enough, but there were a number of roadblocks stopping me from doing this.
Firstly, my Internet connection at home has a dynamic IP address. This means it’s hard to target it because the IP address changes regularly. The solution to this is to use a Dynamic DNS service. The way these services work is to run a utility in the background on your computer and report its current IP address back to the Dynamic DNS service. It ties this IP address to one of its own domain names or a custom domain name that you ascribe to them.
I started to pursue this option. I purchased my own domain name and got an account at Dynu, one of several free dynamic DNS services and attached my domain name to it. I installed the IP Update Utility on my home computer, added my account credentials and successfully started reporting my IP address back to Dynu. However, there was a problem…
My computer is always connected to a VPN. Thus, whenever the IP Update Utility retrieved my IP address, it was getting the IP address of my VPN, not my public IP address. Thus, if I tried to use that to access my home network, I’d instead end up at the servers of my VPN service.
