Hello All: I'm looking into using Microsoft IAS and Windows NT4 PDC to authenticate VPN client users who are accessinga VPN 3000 concentrator. I want home VPN client users to utilize the NT4 PDC for their login authentication. The VPN 3000 concentrator is located on the outside interface of the PIX while the NT 4 PDC is located on the inside. My questions are: a) Should I combine the PDC and IAS into one server? My preference is to use separate servers, and would this scenario works? b) What ports should I open to allow Radius and NT authentication from the outside to the inside? Thanks. Ken
