Hello,
I have configured a Cisco 2611 for AAA (Authentication, Accounting, Authorization)Instructions, but the router cannot access the internal radius server. Another problem: I have published Our DNS Server, but when I try to use the DNS Server from the Console of Our Router, the Router cannot find my DNS Server, and ISA Server logs this access as "Spoof attack"!
Here is a diagram of a part of Network:

A "spoof" attack is when packets try to enter your network and those packets of a source address *of* your network.
Your ISA server needs to have an exception for the IP address of your internal interface of your router.

Dear Mick,
Hello,
Thank you very much for your reply. But how can I craeate an "exception" for the IP address of my Router? There is a RADIUS Server in the internal network, that the router must send information for authentication users and etc to this Server, but now the Router can not connect to this Server.
I define the internal DNS Server for the Router, but the Router cannot resolve any address, because the ISA Server denied access of the Router to the internal network.
If possible please, help me.
Regards
Mohammad Samini
