Below is additional information about potential problems you may encounter when using any of the above solutions.
- Firewall - Any firewall protecting your home, work, or school network must be open for many of these software programs or services to communicate with other computers. If you have a software firewall program running on your computer you must unblock or open the port for the program when prompted. Some schools and corporations have a hardware firewall that will block almost all outside Internet traffic making it difficult if not impossible for many of these solutions to work.
- Static IP vs. Dynamic IP - Many of the programs will require you to specify the IP address of your computer. If you do not have a static IP address this address will change each time you connect to the Internet. This can make it difficult to connect if your computer is consistently changing its IP address.
- Modem vs. always on connection - If your home computer is connecting to the Internet using a Modem instead of an always on connection such as a broadband connection you must keep your modem connected in order to connect to the computer.
- Plug-ins and additional software - Many of the online services that allow you to remotely connect to another computer over your browser will require that a plug-in be installed into the browser or a third-party program be installed. Some work and school computers may prohibit you from doing this.
- Computer must be on - Finally, the computer you want to connect to must remain powered on.
