APs in Bridge Mode and external server (ClearPass) for Captive Portal authentication?

Hi all,

 

I understand that the basic captive portal authentication isn't supported in Bridge Mode because the captive portal page is hosted by the controller. However should this work with ClearPass?

 

Many thanks

I don't think so.  The controller still needs to hijack the DNS and redirect the client to the portal, whether it is hosted internally or externally on Clearpass.


If my post is helpful please give kudos, or mark as solved if it answers your post.

Captive portal in general is not possible in bridge mode.


Thanks,

Hi,

 

Do you mean when locally deployed, it is possible it just depends on your underlying network and connectivity.

Captive Portal is not possible when the forwarding mode is bridged.

Well seems like then the limitation is with the Aruba. I managed to get it working with aruba IAP's, juniper WLA in bridge mode, Meru AP's in bridge mode. Both the controller and the CPPM was located in a DC with bidging enabled in all these product vendors.

Yes, captive portal works in bridge on the Instant architecture. If you absolutely need bridge captive portal, Instant is the way to go. 

Best practice design with controllers is tunnel.
