4. Firewall Setup
1. If you are using DHCP from your router then you are going to want to create a reserved IP address that is mapped to the MAC address of the nic card in the machine that is going to be remotely accessed.
2. Once that is completed then you are going to need to setup port forwarding to that reserved IP address.
Forward port 22 for ssh tunnelling
Forward port 5900 for direct connection to a vnc server
Forward port 3389 for direct connection to remote desktop
Step-By-Step Instructions on setting up Port Forwarding on many different routers.
To open Windows Firewall
1. Click Start and then click Control Panel.
2. In the control panel, click Windows Security Center.
3. Click Windows Firewall.
1. Make sure that the "Don't allow exceptions" is NOT checked and then click on the Exceptions tab
2a. On the exceptions screen if you want to allow remote desktop click on the remote desktop checkbox and press ok.
2b. If you are going to be connecting through the secure ssh connection to remote desktop or the vnc server then you want to click on the "Add Port" button and put in port 22.
2c. If you are going to be connecting directly to the vnc server without the ssh tunneling then you need to select "Add Port" button and put in port 5900.

Some ISP's or firewalls may block the default port 3389, and changing the port may be a successful workaround.
Basic Summary Below:
Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
Modify the decimal value of the portnumber and reboot the computer.
When connecting to this computer with a different port number you will need to manually specify the port. If you are going through a SSL tunnel instead of localhost:3389 you would use localhost:portnumber. If connecting using Remote Desktop directly you would connect as yourhomeip:portnumber.
