A virtual local area network or VLAN is a method of creating independent logical networks within the same physical network. In this way, it is possible to reduce the broadcast domain, or in other words, restrict the ability of a device to enter a certain network.

This allows the connected computers to not be able to communicate with each other, it is very useful because this way you can protect your private information from others. In addition, the virtual networks created will be faster since the traffic will be reduced to a certain number of devices.

Let’s go on to explain how the process is, the steps to follow may vary a little depending on the company that provides the connection. We will try to cover this topic as generally as possible, but if you have problems it would be best if you contact your service provider.

These are the steps you must follow:

  •  The first thing is to connect the “Ethernet” cable from the ONT to the WAN port of the Router.
  • We connect that same cable to our computer.
  • We access the router configurations portal by typing “” in the search engine.
  • We write our username and password to enter.

At this point, the configuration will depend on your internet provider, below we will indicate the configurations of the most popular operators in Spain.

Institutional and corporate networks currently use this configuration for security reasons or to limit access by unwanted users. They protect your information and at the same time efficiently organize your network in hierarchies that can be managed from the central network. Let’s see for each operator:


You will activate the “special ISP requirement” option . We select the option “Movistar triple VLAN” then on the internet we write in VID 6 and in priority 1, for IPTV we write in VID 3 and in priority 5 and finally in VoIP we write in VID 2 and in priority 4. It only remains to give it next to save the data and that’s it.


For Vodafone we go to “quick internet configuration” we give “No” and then to “internet configuration”. Here you can choose the default configuration of the Router, only in the option “internet” write in VID 100 and in priority 0 then for IPTV the VID equal to 100 AND “0” in priority and for VoIP the VID in 2 and the priority in 4. Finally, you click on next and that’s it.


After entering you enter “internet settings” then press “No”. Select “Automatic IP address” and activate the option “Special requirements of the Internet Service Provider”. You look for the option “Manual adjustment” and you write in all VID 832 and 0 priority. Select the option “Next” and that’s it.
