Captiv portal and vouchers integration with ssid on wlc 9800
-
Hi,
Im looking how to configure integration of Captive portal and Wlan on Cisco Wlc 9800.
The idea is to have guest SSID configured on Cisco wlc 9800 and integrate it with external in this case Captiv portal web.
That guest SSID should be redirected to Captiv Portal where I should type voucher earlier generated which gives me access to internet.Is there anyone who did this configuration and can help to find the right option to achive it?
Best regards,

Cisco ? Dono what that is. It better be an access point.
What you want is this :
As I use 3 access points, I used a dumb switch.
As the connected client device are not my friends, just people that need an Internet access, I use a dedicated LAN interface (OPT) for the captive portal.
My own stuff is hooked up to the LAN interface, not shown in the image.The access points don't need any special setup. Just an SSID, and typically, you remove the WPA password, so the SSID will be an 'open' network.

@Jozy you can run captive portal on the cisco controller, or just let cisco provide the wifi and run the captive portal on pfsense.

@Gertjan @johnpoz
So the situation is that when I try to connect to SSID guest it redirects me to Pfsense
the problem is that voucher are enabled and generated and when testing it works (as you can see from the picture )but when trying to reach Captiv Portal, pfSense asks me to type username and password instead of vouchers.
What could be the problem, on Captive portal side or SSID doesn't send right path or there is some other issue?? :(

that isn't captive portal, that is just the gui web page.

@johnpoz perhaps I got it wrong.
What should I get?
How to get vouchers to autenticate instead of usename/paasword? -

Did you saw the login page ?
The default (build in) login page will ask for a user name and password. if you have activated Voucher it will also show a third entry line, where the voucher must be entered.
Confusing for your portal victims ? I agree !Now, remember that you saw this : check the option "Enable to use a custom captive portal login page" and you' see :
Extract the captive portal login page with your browser to see what it looks lie.
Html of course, so no big deal.
Look also at /etc/inc/captiveportal.inc - search the function get_default_captive_portal_html() to get the default captive portal htm
There you can see how it's done.
In your case, make your own identical html file, but remove these two :<input type="text" name="auth_user" placeholder="{$translated_text1}" id="auth_user"> <input type="password" name="auth_pass" placeholder="{$translated_text2}" id="auth_pass">Don't forget to create "error" logout page also. Its nearly the same file as your login page, with one line added (the line that shows the error message).
After login, where do you login redirect your clients to ?
Remember this one ?

which means : don't run the portal on your LAN.
You can, just be ready to assume the consequences. -
@Gertjan Thanks for the effort.
That's the problem since as I can see everything is enabled but I still don't get third entry for vouchers, only for username and password not vouchers. hm
you can see below fi something is wrong:
Is this ok for the local database?
I dont know what is wrong, is there some compability problem. PfSense version is 2.7.2 ?

@Jozy looks to me you have it set to use custom, but don't actually have custom setup
-
@johnpoz hm not sure what do you mean when you say that?
-
@Jozy your read @Gertjan posted write where you edit the template and add your voucher section..
edit: so what exactly is happening? You want to get rid of the username password prompt like @Gertjan was talking about? Because I just fired up captive portal on my guest network.. Connected with iphone, got the captive portal - and used a voucher to login.. It was pretty clicky clicky
And as I said before - this is not the captive portal, this is just the normal gui login
The default out of the box click,clicky captive portal is the image I posted above where I put in my voucher.
Your not running into a issue where your gui is listening on the captive portal port? I believe the captive portal is like 800x where x can change, etc. Are you using something like that for your web gui port? Example Just turned on the captive portal again to see what port its on, and its on 8002
[24.03-RELEASE][admin@sg4860.home.arpa]/root: netstat -anl Active Internet connections (including servers) Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp6 0 0 *.8002 *.* LISTEN tcp4 0 0 *.8002 *.* LISTEN -
@johnpoz Please if you can help me what exact lines I have to add in "captiveportal.inc" instead of
<input type="text" name="auth_user" placeholder="{$translated_text1}" id="auth_user">
<input type="password" name="auth_pass" placeholder="{$translated_text2}" id="auth_pass">??
As well, what is URL for Captive Portal I should use and put to WLC if I want redirection to ?
Im using this - https://x.x.x.x/services_captiveportal_zones.php :)
I have downloaded and uploaded html from page to Captiv portal content but nothing -

If your going to do the captive portal on pfsense, there is nothing to do on the wlc.. Its just the wireless connection - pfsense would handle the captive portal you enable in pfsense on the network your clients are connecting to via wireless.
I would suggest you get that working before you look into editing how the captive portal page looks.
If all your going to ever use is vouchers, you can edit the page to only show that as an option. But vouchers will work even if it presents the options of username/password.. But get your captive portal working before worry about how the page looks would be my suggestion.
You can always pretty up the page once you know its functioning ;) And I think there is even some 3rd party tools you could use to print out vouchers with qr codes on them, etc.
-
@johnpoz maybe I didn't provide enough info.
First im using virtual open source pfSence version 2.7.2.
Second, I would like to have SSID guest configured on WLC which is only for guest connected to captive portal and providing vouchers if possible.
If I'm not asking to much I would like if we can have short call as I can share you my screen for 10-15 min just to go through this setup since you know it already and can see what is the problem :)Best regards,

@Jozy this is really just click click on pfsense. If your trying to do something with captive portal on wlc and forwarding it to pfsense captive portal that is where your problem is.
It took me all of like 3 minutes to get captive portal working on my wifi guest network.. I enable the captive portal on it, pretty much all default really and it was done. The longest part of it was having to remember where to download the csv of the vouchers I created so I could see a voucher number.
If you want to use the pfsense captive portal - until your ready to create a custom page.. Keep this unchecked
I really wouldn't even worry about users or vouchers until when your client connects he sees that login page.. If so then your captive portal is working.. Then you can create users or vouchers..
This is really click enable and pick the pfsense interface you want to run the captive portal on, and hit the save button on the bottom of the page.. There isn't much else to it.
On your wlc don't setup any sort of captive portal, normal in a captive portal there is no login to the wifi.. But you could use just a psk auth to connect the client to the wifi if you want to make sure your captive portal is working before you move to no auth.
-
When this is activated - vouchers :
and you use the default portal settings : this - NOT checked :
you see this as your portal login page :
If the user has a voucher code, then they should use the third text box marked Voucher code.
-
@johnpoz @Gertjan I completely agree with you it is just straight forward with only few clicks but whatever I try it doesn't want to open third party for vouchers.
So, when connecting to SSID it redirects me to
so, you can see here I cant get third party for vouchers.
Maybe the problem is what you have mentioned at the beginning with about:
/etc/inc/captiveportal.inc - search the function get_default_captive_portal_html() to get the default captive portal htm<input type="text" name="auth_user" placeholder="{$translated_text1}" id="auth_user"> <input type="password" name="auth_pass" placeholder="{$translated_text2}" id="auth_pass">If yes this is something Im not sure how/what to add what lines are correct?
Best regards,
Jozy -
@Jozy that is NOT the captive portal
The only way you would see that is if you have your wlc redirecting.. That page would be available on whatever your normal gui ports are? 80/443?
The captive portal is going to be on some 800x port..
Or your captive portal isn't even running and your just hitting the pfsense IP on whatever ports your normal web gui is listening on.
edit:
Here.. did a quick packet capture of what happens when client hits the captive portal.. See how the redirection sends it to the port the captive portal page is being hosted on.

@Jozy
Removing this :
will remove this :
But that's not the issue right now.
Let's keep it for later.
The device you use to connect to the captive portal, what IP does it huse ? What network mask ? What DNS does it use ? What is the gateway ?
Same question : what was the DHCP lease you received ?On the pfSense side : what is the IP of your captive portal ?
Do you remember that I said above, two times already : to start a first captive portal, do not use your pfSense .....
-
@Gertjan Yes, I know if we remove lines form /etc/inc/captiveportal.inc will remove user and password functions.
The device I'm using for this is android, with Ip address x.x103.48/24 and gateway 103.1 given from DHCP server configured on WIN server, actually I get it when try to connect to SSID which redirects me.
I'm using internal DNS x.x.112.10 and gateway x.x.112.1.ip address of pfsense is x.x.110.155 and that one I'm using for pfsense and as well on WLC side for redirection.
https://x.x.110.155/services_captiveportal_vouchers.php?zone=captivportal?switch_url=https://192.0.2.1/login.html&redirect=<website-name>
you mentioned this" Do you remember that I said above, two times already : to start a first captive portal, do not use your pfSense ....."
Does it mean I have to have different ip address on different subnet configured for Captive Portal, not using ip address of the pfsense
