Videotron Business Link – Port Block!!!

Hi,

I have a surprise last day with Videotron Business Internet Link, they block some ports! You need to discuss with several level, because Videotron employees doesn’t seems to have the information or not all of them have the information.

I mean, you can block port on a residential account and I totally agree with that, but a business link, it’s not an option and also there’s no agreement you can sign with them to have those port unblock

This is the port Block and confirmed by a security engineer.
