You may well know that Digi uses a wide variety of routers, both those it currently installs and those it installed back in the day. However, the process to open ports on a router has a very particular detail if you have contracted a rate with this company. Basically, because we will need to pay to open them. Otherwise, the operator of Romanian origin will not allow us to carry out this process.
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 for the operator ‘s Conexión Plus service.
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 find ourselves with the fact that we will not be able to open VPN ports or 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 the case of Digi, all Internet rates are accompanied by 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 Conexión Plus service. The main inconvenience that we find is that we will have to pay 1 euros 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 haven’t activated it yet, you can contact their Customer Service department by calling 1200 (free from the Digi network) or 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 contract this extra service for which we will have to pay 1 euro more per month in our rate. Specifically, if we need to 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.
