You may need a protocol rule allowing the request, especially if the Radius Client is a secureNAT client. UDP ports 1812,1645 for authentication and 1813,1646 for accounting.

My private users use RADIUS authentication to get permission for accessing Interent. My RADIUS is located in public network. The question is, 1. how to "pass" the RADIUS information through ISA Server? * To where, for what, in what form? ISA supports passthrough authentication for web requests. How the client got his credentials is (almost) irrelevant to ISA 2. How to test that SecureNAT is working? * Try to "ping <IPAddress>" from a secureNAT client. NB : My private network use 10.x.x.x IP addresses. And my public one, use Class C IP Address * That sounds fine. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: gregorymc@xxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
