Cisco WLC can not redirect to web auth

Dear guys

My network diagram is:

This mean my external web server is located in another network. I setup like Cisco guide but:

- When I set WLANs -> Security -> Layer 3 -> Layer 3 Security = none, i can access the internet, i try access my external web auth by manual, it's ok.
- When I set WLANs -> Security -> Layer 3 -> Layer 3 Security = Web Policy and Preauthentication ACL = my ACL set same as  guide, my laptop could not redirect to web auth, it shown:

Try:

ERR_CONNECTION_CLOSED
but i could access my external web auth by manual.
- When I set WLANs -> Security -> Layer 3 -> Layer 3 Security = Web Policy and Preauthentication ACL = my ACL - set allow all traffic, my laptop also could not redirect to web auth, the result same as situation 2.
I think my problem related to Preauthentication, i'm not sure if my external web auth is located in different network with cisco WLC, which Preauthentication ACL i have to setup.
Thanks for your support.

Hello,

Did you configure the Web Auth type as external ?

Dear  Mr.Alex

yes, i did

i already added: 

External Webauth URL: my authen website link

I think this problem is related to Preauthen ACL, when i set  Preauthen ACL allow all, i can access internet immediately ...

Hello,

Can you please share your ACL configuration ?

Thank you,

Alex-
