Hi Roger, there are multiple solutions for either NAC/ECP or Internal/Guest portal for your scenario. One of them is what Andre mentioned. Others can include : policy based routing, dns cache with Nac, split tunnel. One think I want to note - if you decide to go with what Andre proposed, make sure you set very low dhcp lease time for your 'non-authenticated' (or Unredistered) users , otherwise when client will be changing subnet there will be high chance that it will keep previous IP address. The lease time I usually set for that topology is 30 or 20 seconds, meaning that topology is dedicated and can be used only for on-boarding purpose.
