Issues getting url-redirect working with Cisco ISE

Question

Hi,
I am currently doing a Proof of Concept using Cisco's new ISE product. I am having issues getting the url-redirect raidus attribute working. I have read the troubleshooting document and everything in it points to it should be working. By debuging the radius information on the switch I can see that its passing the url-redirect to the switch  which in my case is was https://DEVLABISE01.devlab.local:8443/guestportal/gateway?sessionId=0A00020A0000001604D3F5BE&action=cwa. Now to remove DNS issues etc from the equasion if I copy and paste this URL into the client browser it takes me to the correct place, and I can login and it changes VLAN's accordingly. Now as far as I know the client should automatticaly be redirected to this URL which is not working. Below I have included one of the debugs to show that the epm is in place.
DEVLABSW01#show epm session ip 10.0.1.104
    Admission feature:  DOT1X
              ACS ACL:  xACSACLx-IP-PRE-POSTURE-ACL-4de86e6c
     URL Redirect ACL:  ACL-WEBAUTH-REDIRECT
         URL Redirect:  https://DEVLABISE01.devlab.local:8443/guestportal/gateway?sessionId=0A00020A0000001604D3F5BE&action=cwa
I have also attached my switch config. Any help would be greatly appreciated.

Answer 1

So im also doing ISE for the first time and i knew it may have been a bit tough however i didnt forsee my following issue.
everything is working as expected other than every now and then (intermittent) the ISE Central Portal does not display on any device -android, windows, etc..... i checked and checked the configs, had probably about 10 TAC cases open..... this weekend i ripped out the main components, setup in the offfice and tried to replicate the issue....i could...what i noticed is that without Internet the ISE Portal didnt actually display....it sounds weird but thats what im seeing.....As soon as i plug into Internet Link into the equation, the portal page comes up.....im able to replicate it every time... Currently, i placed back into the customer network and im now looking down at the routing/firewall......
my issue is that i cant really explain why the Internet affects the Central Auth Page.... In any event. im working backwards, tomorrow im bringing in a second link and doing NAT on a cisco router to bypass the checkpoint firewall....ill know if its checkpoint or if im barking up the wrong tree....
if anyone can explain why, it would help out a great deal..
My setup BTW is
1. WLC 5760 - Not latest code but latest stable (recommended by the TAC Engineer)
2. ISE 1.2 - Doing simple Wireless only implementation
3. 3650 - Just acting like a switch - no ACLs etc - just a switch
4. Integrated into AD
Ill post back with any findings if i make any headway - BTW, i didnt like this at all as other solutions are so much simpler, BUT, i can now see how powerful this could potentially be for the right type of customer...
thanks again how i can get some feedback
