Redirection when traffic goes to port 80

[JT40]

Hello,

I need to block the traffic to the port 80, which easy, but I also need to set up a redirection so I know why it's happening.
The redirection would redirect the traffic to some custom internal page of PFsense.
Before to start, is it even possible??

There are a few scenarios why I need it:

1. Standard HTTP traffic through browser, sometimes I visit such websites, and I need them, but I'd like to know why it was blocked instead of remembering or inspecting my FW rules :D .

2. Sometimes banks have some part of the website in HTTP, mostly for malfunctioning, so I would't like to proceed when there is such scenario, a redirection would help to spot the problem right away.

3. Same for the Apps that mostly use APIs, but in case of a failure, it's up to the App API to thrown the failure (and that's not predictable or manageable by me), unless I'm in Webview.
