Question - Does the provider (INEA) block ports to customers?

Good morning,

I have been using INEI's fixed-line Internet connection service for over a year without any problems. Now, however, I want to open one port on the Cisco EPC3925 router and it fails. Setting up and directing the DMZ to the computer does not work. Even setting the router to "Bridge Mode" and connecting directly to the computer does not work either.

The question is: are there any ports that the client can use? I hope that not all (rather none) ports are blocked by the operator.

Do operators in Poland usually block ports?

Thank you.

Their equipment, so they do what they want (but 100% INEA doesn't block).

Thanks. I wrote to INEA support and they replied that the ports are not blocked from the provider's side. They wrote that they "configured the router" and that I should disconnect from the power supply so that it restarts, and then it should work. I did so and now it works properly. I can set the ports as I want.

First, make sure your Cisco modem is assigned a public address.

Virtually everyone blocks certain ports, e.g. 139 etc.

It seemed to me that a few ports (usually numbers below 1024) are usually blocked by the ISP. In Sweden there are generally no other restrictions, but I heard that in the UK they block more. I didn't know if there is a rule in Poland, but it turns out that there are no restrictions. Thank you for your help. :)

Now I'm happy because I can connect to Raspberry Pi outside the house.

I dig it up because I signed a contract with INEA several days ago.
1. It is impossible to log in to their router with full permissions and only as a user.
2. They can check and change the router configuration remotely.
3. The public IP is not shared and thus opening tcp or udp ports on the router will not bring any effects unless the client has a material reason to have such a public ip then it is obtained without additional charges.

I think this is off topic and I suggest closing it.
