    No, I meant to redirect with the information at the end.

    Try this:

    when HTTP_REQUEST priority 400 {
    	set mac [LINK::lasthop]
    	set ip [IP::client_addr]
    	set url [HTTP::uri]
    	switch -glob -- [string tolower [HTTP::host]] {
            	"123.45.67.890"     { HTTP::redirect "https://example.com/portal/step1.html?MACAddr=$mac&IPAddr=$ip&OrigURL=$url" }
    	}
    }

    Forgot to say...

    Don't forget the mac address you will get is the last device mac address.

    If the client is not in the same network as the F5, it is not going to be the client mac address.
