IF you are still dealing with the issue, I suggest you look into a remote access solution.
A very simple way to remotely access a computer is thru the use of Google's Chrome browser. It allows for an RDP (Remote Desktop Protocol)-like experience while being independent of your ISP's dynamic IP addresses.
In other words, you can use a browser extension installed into your Chrome browser, in order to access remote assets.
Hope this helps.
