I'm not saying you can't be connected in more than one way, I'm saying that it's a special case that is unusual enough that it ought not to be easy to mistakenly claim you're going to do. As far as I know, Rob, at the current moment you're the only one doing this.

Hmm... disappointing. I would hope everyone who is BGP routing would be doing that. I am not the only one, your gateway is doing the same thing :-)

A quick check returns the following subnets being both BGP and Tunnel routed:

44.135.193.0/24 44.136.227.0/24 44.137.0.0/16 44.161.230.0/24 44.161.252.0/22 44.188.128.0/20 44.208.0.0/16 44.48.16.0/24

Two or three times a week I get applications which have simplemindedly checked all three boxes. Most of these people have no idea what they're asking for

Most applications of portal registrations I get are wrong or strange. It appears that the thing is confusing to newcomers.

I'm open to any suggestion that will keep me from having to go through this process over and over again. Perhaps making 'Direct' a link which brings up an intermediate page which presents a blurb about what checking Direct actually means and demands that they confirm that they're really going to get a BGP announcement from their ISP? Other ideas?

It could be done with a simple Javascript on the page that presents a pop-up or reveals some explanation on the page when the checkmark is set ON.
