[c-nsp] PPPoE and HTTP Redirect

Hello all, I’m looking for some recommendations.  I have a customer, an
ISP, who is doing PPPoE for residential and “some” smaller business
accounts.  PPPoE terminated on an ASR9010, DaloRadius for authentication
and IP assignments.  DaloRadius is configured for static IP per customer.
All that is working fine.  Recently, we enabled HTTP redirect on the 9010
because the customer wanted to try out a walled garden for past due
accounts.  So, past due accounts are handed a static 10.x.x.x IP, and
password changed.  Next time customer re-auth’s, they get the 10.x IP
because of the bad pass, and put into the HTTP redirect jail, and are
supposed to be redirected to a http site.  “Sometimes” http redirect works,
sometimes it doesn’t.  It seems as though it depends on the destination
address the end user is trying to go to.

At any rate, the ISP is wanting to investigate something else for PPPoE and
their walled garden.  Has anyone used anything else successfully for PPPoE
auth, and walled garden jail?  Something that is a bit more seamless?  The
ISP has their own home-brewed billing/account software, and just wants a
redirect to their landing page to work each time when a customer is
disconnected for non-pay.  I have not done a lot with PPPoE myself, so
reaching out for possible 3rd party solutions that can do all-in-one.
