Redirect HTTP for PPPoE users with radius attribute

Hello.
For users with negative balace we just supply “Filter-Id” attribute for PPPoE users with an ACL, that blocks all, but stats/news websites and DNS server, but sometimes they do not want to visit such sites and prefer to call tech.support with questions like “why my favourite website doesn’t open”.
But I’d like to add something like redirect, so users are ALWAYS redirected to stats server if they have negative balance.
Is it possible to do this?
I’ve tried “Mikrotik-Advertise-URL”, but I think it’s work only in a hotspot setup and not PPPoE.

hmmm… what’s with DST-NAT for blocked users?

I’m thinking about it, but how can I make dst-nat for only specific users?
Set up a chain which will be used as “Filter-Id” and set action to “jump=dstnat” - will this work?

oops… but you may assign addresses from different IP pool, and redirect only those customers
