Re: ISP port blocking practice

Blocking the well known port 25 does not block sending of mail. Or the message content.

Blocking various well know M$ protocol ports does not block remote file access. Or control the type of files that can be accessed.

I think the relevant neutrality principle is that traffic is not blocked by content.

So, no, blocking any port is NOT against the idea of Net Neutrality.
