Cisco ISE guest portal redirect not working after successful authentiation and URL redirect.

Question

Hi to all,
I am having difficulties with an ISE deployment which I am scratching my head over and can't fathom out why this isn't working.
I have an ISE 3315 doing a captive webportal for my guest users who are on an SSID.  The users are successfully redirected by the WLC to the following URL:https://x.x.x.x:8443/guestportal/Login.action?portalname=XXX_Guest_Portal
Now when the user passes through the user authentication splash screen they get redirected to https://x.x.x.x:8443/guestportal/guest/redir.html and recieve the following error:
Error: Resource not found.
Resource: /guestportal/
Does anyone have any ideas why the portal is doing this?
Thanks
Paul

Hello,
As you are not able to  get the guest portal, then you need to assure the following things:-
1) Ensure that the  two  Cisco av-pairs that are configured on the  authorization profile should  exactly match the example below. (Note: Do  not replace the "IP" with the  actual Cisco ISE IP address.)
–url-redirect=https://ip:8443/guestportal/gateway?...lue&action=cpp
–url-redirect-acl=ACL-WEBAUTH-REDIRECT (ensure that this ACL is also  defined on the access switch)
2) Ensure that the URL redirection portion of the ACL have been  applied  to the session by entering the show epm session ip   command on the switch. (Where the session IP is the IP address  that is  passed to the client machine by the DHCP server.)
Admission feature : DOT1X
AAA Policies : #ACSACL#-IP-Limitedaccess-4cb2976e
URL Redirect ACL : ACL-WEBAUTH-REDIRECT
URL Redirect :
https://node250.cisco.com:8443/guestportal/gateway?sessionId=0A000A72
0000A45A2444BFC2&action=cpp
3) Ensure that the preposture assessment DACL that is enforced from  the  Cisco ISE authorization profile contains the following command  lines:
remark Allow DHCP
permit udp any eq bootpc any eq bootps
remark Allow DNS
permit udp any any eq domain
remark ping
permit icmp any any
permit tcp any host 80.0.80.2 eq 443 --> This is for URL redirect
permit tcp any host 80.0.80.2 eq www --> Provides access to internet
permit tcp any host 80.0.80.2 eq 8443 --> This is for guest portal
port
permit tcp any host 80.0.80.2 eq 8905 --> This is for posture
communication between NAC agent and ISE (Swiss ports)
permit udp any host 80.0.80.2 eq 8905 --> This is for posture
communication between NAC agent and ISE (Swiss ports)
permit udp any host 80.0.80.2 eq 8906 --> This is for posture
communication between NAC agent and ISE (Swiss ports)
deny ip any any
Note:- Ensure that the above URL Redirect has the proper Cisco ISE FQDN.
4) Ensure that the ACL with the name "ACL-WEBAUTH_REDIRECT" exists on  the switch as follows:
ip access-list extended ACL-WEBAUTH-REDIRECT
deny ip any host 80.0.80.2
permit ip any any
5) Ensure that the http and https servers are running on the switch:
ip http server
ip http secure-server
6) Ensure that, if the client machine employs any kind of personal  firewall, it is disabled.
7) Ensure that the client machine browser is not configured to use any  proxies.
8) Verify connectivity between the client machine and the Cisco ISE IP  address.
9) If Cisco ISE is deployed in a distributed environment, make sure  that  the client machines are aware of the Policy Service ISE node FQDN.
10) Ensure that the Cisco ISE FQDN is resolved and reachable from the  client machine.
11) Or you need to do re-image again.
