Adding IPS Modules to IPS

Jason Regan — Mon, 11 Mar 2019 04:03:23 GMT

Have got ISE 1.2 running and have my firewalls authenticating against them and need to get my IPS modules authenticating as well but don't seem to be able to get them to.

My settings on teh IPS Device are as follows

Servier IP Address - {ISE Address}

Authentication Port - 1645

Timeout (seconds - 3

Shared Secret - {Shared Secret}

However ISE is rejecting the request

	11001	Received RADIUS Access-Request
	11017	RADIUS created a new session
	11015	An Access-Request MUST contain either a NAS-IP-Address or a NAS-Identifier or both; Continue processing
	15049	Evaluating Policy Group
	15008	Evaluating Service Selection Policy
	15006	Matched Default Rule
	15041	Evaluating Identity Policy
	15006	Matched Default Rule
	15013	Selected Identity Source - ActiveDirectory
	24430	Authenticating user against Active Directory
	24402	User authentication against Active Directory succeeded
	22037	Authentication Passed
	15036	Evaluating Authorization Policy
	24432	Looking up user in Active Directory - $$-jregan
	24416	User's Groups retrieval from Active Directory succeeded
	24420	User's Attributes retrieval from Active Directory succeeded
	15048	Queried PIP
	15048	Queried PIP
	15004	Matched rule - Default
	15016	Selected Authorization Profile - DenyAccess
	15039	Rejected per authorization profile
	11003	Returned RADIUS Access-Reject

Do I need to set a new condition based on some specific piece of information for ISE to recognise this devices request?

Any advice would be greatly appreciated.

Many thanks in advance

Jason

Jason,

Looks like you're landing on default authorization policy (DenyAccess).

Add an authorization policy what would match the network device/AAA client of your IPS, make sure it's on top.Take if from there.

Also 1645 - old port, ISE should be listenning to old and new, but 1812 is what you would typically see for any other device config.

Can you post a screenshot of your authorization policies, along with IPS settings in ISE

Hi Tarik,

Here is the condition used in my Authorisation Policy for allowing access to the IPS module

ActiveDirectory:ExternalGroups EQUALS {AD Group of which I am a member}

AND

Network Access:AuthenticationMethod EQUALS PAP_ASCII

AND

Radius:NAS-IP-Address EQUALS {IP Address of the module}

I'm not sure what you mean by "IPS settings in ISE", all I have done is add a device using the IP address and shared secret

Thanks

Jason
