I did it, man! the modem in bridge mode had to have the same port configs, but pointing to the router address. Thank you for the patience! It isn’t fast, but works.
Also, about the tests:
1- I couldn’t open even in other public gateways as cloudflare or infura.
2- When I asked you to try the file, you probably pinned it, and I could open it in the public gateway, so I asked other to pin another file that I coudn’t open. When he pinned it, I could see it as well.
Know a have a bridge mode modem pointing the ports to the router, and the router poiting to my desktop. I realized that que number of peers increased too. Before it had about 250~400, and now ~740.
Also, I want to ask you: there is a precise command to see who is pinning a file? I saw in a topic that dht findprovs would to it, but with some tests, I realized that is more like a footprint of who interacted with the file.
Thank you again!
