If you need help in setting up your router port forwarding just send us an email.
There are many videos on Youtube that show how to port forward, while you may not have the exact router these videos use the principle is the same for all routers.

Port forwarding is the process that your router or firewall uses to sort the right kind of network data to the right port. Computers and routers use ports as a way to organize network data. Different types of data, such as web sites, file downloads, and online games, are each assigned a port number. By using port forwarding, the router or firewall sends the correct data to the correct place.

A firewall protects your computer by blocking unauthorized information. If a firewall blocked all the incoming and outgoing data, the computer would be unable to access the Internet. When you want some data to go through your firewall, and you want it sent to a specific location, you can set up port forwarding. Port forwarding gives the firewall instructions about which types of data are allowed and how they should be directed.

Information on the Internet is associated with a port. Web pages, for example, are typically assigned port 80. File transfer protocol (FTP), often used for downloading and uploading files, typically uses port 21. Online games may use a number of different port numbers, but often choose numbers in the thousands.

Know your aircraft inside out.

You must be able to track and take bearings from a VOR.

Execute a full ILS landing, with ATC vectoring.

Have a good knowledge of ATC radio procedures.

You can obtain training for any of these procedures, just ask when you are on TS3 or post a request in our forum.
