For the Sitrad Remote to access the Sitrad Local remotely you need to know the IP address of the machine where the Sitrad Local is installed. No problems so far, since the server IP where the Sitrad Local is installed can be checked by opening the server Internet browser to access any page that shows the IP, such as www.ip-adress.com.

The problem appears when the Internet service uses a dynamic IP. In this case, the computer IP address is changed at times preventing the Sitrad Remote to use the old IP to access it.

One way to solve this problem is to hire the fixed IP service, which is paid. However, a less expensive way is to use a Dynamic DNS program to solve the problem.

A Dynamic DNS program allows you to use a DNS (Domain Name System) address such as myserver.dns.com instead of using the IP address. This is made possible by installing in the Sitrad Local machine a program that updates the current computer IP address in an Internet server. In the previous example, when the Sitrad Remote tries to access the “myserver” server, the site “dns.com” will return the current IP address of the machine to the Sitrad, allowing for a proper connection between both software applications.
