GPS system 'blocked'
At the moment we implement a GPS system in our company to monitor our trucks. All data of the vendors comes in on port 80. To access the internet we use user authentication.
Problem.
Before we can receive data we first must open any web site and after that our vendor can connect to our SQL database and 'upload' the data. Similair like we update our Sysmantec Virus scanner - first we need to open any web site, after that we can update the virus scanner.
How can we open ports (both for incoming as wel as for outgoing) without opening any web site first?
Thanks,
M.
