[cisco-bba] Help with pop up windows for ADSL subscribers

Thanks to those that replied.
I have tried this using ISG's L4 timed redirect (thanks Paul) and it
appears to do the job. We will probably use this with CoA as we are
already using CoA to push out shaping policies when a subscriber exceeds
their quota.
Here's my radius flat file used to push the L4 timed redirect
cisco-avpair to the subscriber.
redirect-dbtemp          Password = "xxxxxxx"
        Service-Type = Framed-User,
        Framed-Protocol = PPP,
        Framed-Address = 203.17.103.x,
        Framed-Netmask =,
        cisco-avpair = "ip:l4redirect=redirect to ip 210.15.254.x
duration 10 frequency 120",

And I can see the L4 Redirect applied to the subscriber.
test-lns-cr#sh subscriber session username redirect-dbtemp at dbtest
Unique Session ID: 708
Identifier: redirect-dbtemp at dbtest
SIP subscriber access type(s): PPPoE/PPP
Current SIP options: Req Fwding/Req Fwded
Session Up-time: 00:01:30, Last Changed: 00:01:30
Interface: Virtual-Access2.1
Policy information:
  Authentication status: authen
Session inbound features:
 Feature: Layer 4 Redirect
  Rule  Cfg  Definition
  #1    USR  Redirect to ip 210.15.254.x duration 10 frequency 120

My only question is, how do I remove the L4 timed redirect after the
subscriber has updated their credit card information? The way we clear
customers that are no longer shaped with CoA is that we push out a dummy
UNSHAPED policy-map with nothing configured. How would we clear the L4
timed redirect then? is there a way to totally remove it or would we
also need to push out a dummy redirect that lasts a very long time in
the hope that the customer's session would never last that long so they
never see the redirect again??

Hi All,


Just trying to get my head around what technologies might be available
to alert ADSL subscribers that their credit card is about to expire.
I've heard of Front Porch but are there others in the market place?
Basically we want a pop-up of sorts (maybe browser base) to alert the
subscriber that their credit card is about to expire and then maybe pop
up again a week later, etc...
