Re: How to configure NAC to automatically direct the user to the
In a properly designed NAC setup, this should happen automatically. For example if your setup is L2 (the CAS can see the ARP traffic from your clients) then when you browse to any site, the traffic should hit the untrusted interface of the CAS and that should prompt a redirection page. If it's L3 and multiple hops away, then you have to use either PBRs to force the traffic to the untrusted interface of the CAS or use ACLs in certain scenarios.
If you're able to get to the network or internet from your untrusted subnets without the CAS prompting you, then there is another route for the traffic to take and you will have to troubleshoot from that angle.
