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.
