Firewall settingsYou will also need to allow the Remote Desktop client to pass through the Windows Firewall (or any other local firewall you are using). To change settings in the Windows Firewall, go into Control Panel and select Windows Firewall. You will need to go to the exceptions tab an allow Remote Desktop. If you use a third-party firewall, you will need to allow port 3389. You will find instructions on how to do this in the manual for your firewall.
The next thing you will need to do is to configure your hardware firewall to allow access to your Home Server. How you accomplish this task will vary based on which router you use. You must allow TCP traffic on ports 443 and 4125 to pass through your router to your Home Server. Optionally, you can also allow port-80 traffic, as the server will automatically redirect you to the secure site. This is typically done in a Network Address Translation (NAT) selection on your router.
The last thing you will want to do is to set up a dynamic IP address. This can be done from your desktop PC. This service allows you to access your home computer by an Internet name (such as https://mypc.no-ip.net) versus using an IP address. You can find details on setting up dynamic DNS here.
