I'm facing issues with no internet after I access ClearPass Self-Registration CWA. The self-registration only asks for name and email. I'm able to ping/resolve external hostnames, but unable to browse. Has anyone seen this issue on either ClearPass or ISE? My ACLs are below.
Flex Profile Policy ACL
Extended IP access list CAPTIVE_PORTAL_REDIRECT
1 deny ip any host 10.6.1.12 (9 matches)
2 deny ip host 10.6.1.12 any
3 deny udp any any eq domain
4 deny udp any eq domain any log
5 deny icmp any any log (74 matches)
6 permit tcp any any eq www (2632 matches)
Flex Profile VLAN ACL-egress
Extended IP access list acl-internet-only
10 permit udp any eq bootpc any
20 permit udp any eq bootps any
30 permit udp any any eq domain
40 permit tcp any any eq domain
50 deny ip 10.85.2.64 0.0.0.63 172.16.0.0 0.0.15.255
60 deny ip 10.85.2.64 0.0.0.63 192.168.0.0 0.0.0.255
70 deny ip 10.85.2.64 0.0.0.63 10.0.0.0 0.255.255.255
80 permit ip any any

permit udp any eq bootpc any
20 permit udp any eq bootps any
30 permit udp any any eq domain
40 permit tcp any any eq domain
For domain you need to specify two way ACL' i.e.
Permit any any eq domain
Permit any eq domain any
For dhcp I think bootpc/bootps need to adjust also' i.e. keep notice source and destiantion of traffic

Post-auth problems are usually due to WLC not receiving the CoA correctly. Have you got that configured correctly and confirmed the WLC receives the CoA after the user logs in?
