Now, we need to configure the authorization. Radius:NAS-Port-Type: Wireless - IEEE 802.11 Radius:Service-Type : Call Check (Mac Authorization use Call Check on WLC and Switches). We can use the Built-In Wireless MAB condition, which match :
#Cwa authentication successful but no internet cisco ise 2.4 mac#
Now, we need to make sure the ISE is accepting all the MAC Authentication from the WLC and return the profile: In the authorization profile, we need to put the name of the ACL has been created earlier on the WLC: The WLC should already configured as a network device. On the ISE, we need to make authorization profile, and then we can configure authentication and authorization. Basically, we need to permit DNS and traffic to/from ISE.Įverthing is now complete on the WLC. This ACL will be referenced in the access-accept of the ISE and will define what traffic should be redirected (denied by ACL), and what traffic shouldn't (permitted by the ACL). The final step is to create a Redirect-ACL.
We need also to be sure that the radius server have RFC 3576 (CoA) enabled, which is by default. It is also used for Posture Assessment, in which case the ISE would change the user profile based on posture result. The Radius NAC allows the ISE to send a CoA Request to indicate that the user is now authenticated and can access the network. In addition to this, we need to enable Radius NAC and AAA Override. We will configure the ISE to return an access-accept even if the mac address is not found, so that it will sends the redirection URL for all users. We need to configure the SSID to use MAC Filtering. We uses a "trick" (same as on Switches) to get the dynamic authentication URL from the ISE (as it is using CoA, a session needs to be created, and the session ID is part of the URL). The WLC Configuration is pretty straight-forward. The User is prompted to retry his original URL The ISE send a Radius Change Of Authorization (CoA - UDP Port 3799) to indicate to the controller that the user is valid, and eventually push radius attributes (ACL for example). The WLC Redirect to the guest portal (ISE)
The new approach is to use Central Web Authentication. The WLC Redirects back to the original URL. The WLC Authenticate the guest user via Radius The Guest Portal redirect back to the WLC with the credentials entered The WLC Redirect to the guest portal (ISE/NGS)
In case of guest user, we need an external server (like ISE or NGS), as the portal can provide some feature like Device Registering, Self Provisionning. The WLC will then fetch this credentials (sent back via HTTP GET Request in case of external server), and make a radius authentication. In this case, the WLC will redirect the HTTP Traffic to an internal or external server where the user will be prompted to authenticate. The first one is Local Web Authentication. to achieve url redirected session from failed node, active psn node from group has to issue COA.this coa disconnect failed psn from\ session n take it by sending CoA.)/Rect/Subj(Sticky Note)/Subtype/Text/T(Administrator)/Type/Annot>endobj1654 0 objendobj1655 0 obj>/ProcSet/XObject>/Subtype/Form/Type/XObject>streamĮndstreamendobj1656 0 obj/Length 9/Matrix/Resources>/Subtype/Form/Type/XObject>streamĮndstreamendobj1657 0 obj/Subtype/Form/Type/XObject>streamġ40.9029 363.8022 140.9029 370.7478 144 373.8449 cĥ76.6131 370.7478 576.6131 363.8022 573.5161 360.There are multiple ways of doing Web Authentication on the WLC.
