And it is that not only will you have to know exactly how to do it in your Digi router model, but you will have to pay an extra to the operator so that you can have the possibility of opening the ports of your equipment at any time. Specifically, you will have to pay the Connection Plus service operator.
The Digi Connection Plus
In case you didn’t already know, the Romanian operator uses CG-NAT for Internet connections. What does it consist of? It is an IPv4 network design tool. in which the ends of the communication are configured with private network addresses, which end up being translated into public addresses.
In addition, in general, it will not affect our normal use of the Internet. Although, we will meet the fact that we will not be able to open ports or VPN servers, NAS and other services. For this reason, more and more users are calling the operator to contract this service and open the ports.
And it is that, with this tool, it is possible to use the same public IPv4 to associate different private IPv4 addresses at the same time. Therefore, in Digi’s case, all internet fees They are accompanied with CG-NAT, both those that include mobile, and those that are only fiber.
In any case, if we want to deactivate it from our rate, we will have to pay for the service Plus Connection. The main inconvenience that we find is that we will have to pay 1 euro per month to enjoy this alternative. Therefore, we will not have the luck of disabling CG-NAT on Digi for free, except for one port in particular that we will see later.
Which port can be opened for free?
Therefore, if we want to have the option of opening the ports of our Digi router, we must have the Connection Plus service activated. Therefore, if you have not activated it yet, you can contact their Customer Service department calling 1200 (free from the Digi network) or at 642 642 642 (from another operator).
However, as we told you before, there is a particular case in which it will not be necessary at all to hire this extra service for which we will have to pay 1 euro more per month in our rate. Specifically, if we need open port 25 It will not be necessary, since we will only have to contact the Romanian operator to open it. A port that is used by the SMTP protocol to send email. So, if this is our case, there will be no problem, since it will be free and easier.
