You have to configure vlan mapping (at the CAM) for all authentication vlan! After the authentication and posture validation, the NAC client won't give a new IP address, so the client has to have an IP address from the proper access vlan. When you configure these vlan mappings CAS always acquire an IP address from the proper range.
I don't think so. vlan mapping is NOT applicable to Real IP GW.
I've sniffed dhcp-requests from the auth vlans to dhcp server. They are all from the single ip address (NAC Server eth0-trusted). But inside there is the ip address of the untrusted interface - as dhcp relay agent ))
