Orbi RBR750 port forwarding rejects connections for "security reasons". How can it be fixked

Well, maybe, but the folks (like us) who run a web site explicitly to make certain info public, would object that people intercepting the downloads is doing exactly what we want.  It's making our info available to even more of the puiblic. 😉  The packets contain nothing but the IP headers (present for encrypted messages, too), and the info we're trying to get out to the public.  

So what info is there in the download packets of a public file for which interception is a security risk?  There are no passwords or other secret information in either the headers or the packets' data. 

Note that I'm not saying that no network communications contain secrets.  Some, like email transfers, certainly do, but that's normally not done via http links. But http was designed to make posting of public data possible, and was started without any passwords or encryption with the explicit understanding that http was for "public" data that anyone can download.  While we do have organizations that want to limit access to members, and their secrecy is understandable, the fact remains that that's not really why http was invented or why it became so popular.
