I have following queries regarding the implementation of NAC w.r.t remote sites and VPN.My client have already deployed NAC with 5 NAC Servers . 2 of the servers are deployed as NAC L2 OOB virtual Gateway while 3 are deployed as L2 IB Virtual gate way.Now my question query refers to both type of deployment. 1 Do NAC L2 OOB/IB supports VPN clients which connects to a Global VPN server(In another country) deployed on microsoft machine.The Global VPN server lies on another network and our clients get the IP from their Global DHCP servers and access our resources ? 2 What is the best way to implement NAC for remote sites having separate LAN ,should a new NAC NM module is inserted in every remote site or should L3 support be enabled on NAC . What are pros and cons of both.any idea guys.... ... View more
