Currently we have setup NAC to run as a DNS proxy to display a portal page from NAC when wireless devices have been quarantined. We have not setup PBR but are just forcing the client to a VLAN with the DNS server settings in DHCP pointing to NAC and the wireless controller having a policy only allowing access to the NAC DNS.
This seems to be buggy where at times the user is displayed with the page but at times they are not. At it stands this has now completely stopped working.
So question is do I try to debug this issue or is there a better method which will work all the time? Requirement is we want the device to display a message when it has been quarantined.
Is it possible to force a device to a http page from the extreme controller using policy, which we can point to the NAC http page?
Or is there some instructions on how I can setup PBR on the S series switches and C series to help with this?
