Dasan H660GM Router: Access Denied, Configuration & Port Forwarding Issues with New ISP

Hello, I recently changed the internet provider, the service technicians installed the dasan h660gm router for me, unfortunately, I wasn't there and I didn't ask if I could configure this device, but it looks like no, after entering the router's IP address, the router rejects the connection, the router's address is pinging, yes I wonder how they block access to this router ?? How do they configure this router if web access is blocked, is there any other configuration options? I wrote to them because I need port forwarding and so far no response, so my quick question, without configuration, I have to ask them for everything, even for a stupid WiFi password.

Hello. Only the operator has access and the password. And only he can send a service technician to configure this router as needed.

These types of devices are centrally configured by the operator, and for this there is probably a dedicated VLAN and the appropriate application at the operator's, not a simple WWW entry.

Well, I want to understand on what principle I can have access, I understand that I can connect to the router and have to enter a login and password that I do not know, but here it generally rejects the connection, the configuration must take place in a different way than via www, unless it is only a specific MAC address is allowed and mine rejects how I want to configure, I generally think that it is nonsensical to block access to the total router that is with me, I should be able to at least such simple activities as setting up wifi or port forwarding I do not require anything else, and each time calling on service technicians to change two numbers for me to nonsense.

Thanks perhaps it is so.

And here you are wrong.
You give the client a finger and he will tear your hand out.
Not to mention translations like "I didn't touch anything, that's how it was".
The rule is, you don't want to buy your own router, you get what the operator offers. If you want something more, buy your own router and set whatever your heart desires there.

You can manage, for example, via TR-069, SNMP, the operator can also have access to his equipment by device MAC, serial number, etc.

I do not say that the client should give access to various router settings, but to the basic ones, such as Wifii or port redirection, the client will not damage the network, secondly, if the supplier would let me, I would immediately run to the store and buy my router, but it depends on the supplier because I would have to add my router to DMZ, for example, and so I am doomed to their stick or not.

@vudu
This grace or disgrace of the operator is to ensure the customer the reliability of the equipment operation and the stability of the service.
Do you want to tinker with wifi - 2.4GHz is currently useless because such a trash can in the air and 5GHz can work well in one room.
Nobody is interested in what you want, what you want as a customer - the equipment is the operator and he should be comfortable and confidently manage it.

Slowly, everyone begins to move towards denying the client the possibility of any interference in the operator's equipment.

The customer pays the customer requires and the operator has to adapt to it because he will lose customers simple, the operator is not the other way around for the customer, often the operator hurts that the customer can configure more himself than they can, for, without offense to the blonde, an easy password is enough to wifi and everything will work, some clients are more demanding, they need a stable wifi with MAC address protection and limited ip addresses, they need port forwarding etc. do not make clients so called blonde who just need to get them to go, some require more and have to I would like to kiss my hand, I would buy all the equipment myself, so that the operator would only pull the optical fiber to my home

The world is structured in such a way that the goal of the company is never the goal of the client and these interests do not intersect at any stage, and at most they are parallel interests.
Talk to people working in operator companies and you will be surprised to find out that the customer is in last place!
Why on the last one, because if not you as a customer, it will be someone else. Customers change and the business continues.
And the text "I pay, I require" does not impress anyone.
As an example, collect MILLION signatures on the application that the company has something to make available to the client in its equipment and then submit this paper to the operator - you will only amuse the management. The only admiration you will arouse is that you wanted to chase it. You leave the office and your application goes to the shredder - that's it.
There are also issues of the security of the operator's network, provisions between software companies, software licenses, etc., that at no stage the customer has the right to have access to it.
