I can't get Captive Portal login page in any browser else Firefox

jetberrocal

It happens that I have a client that has a Win Server with AD/DNS but without DHCP because it has a Wifi Router that is doing the DHCP Server role.

So I can turn on DHCP on pfsense and configure the router to use the pfsense's dhcp.

How should I configure the pfsense dhcp to register addresses in the AD/DNS?

Once I get this dhcp running I can turn on CP in pfsense

No idea why you wouldn't just use Windows DHCP in that case.

I tried Captive Portal with DHCP in the AD, but it did not work. Also in this thread was directed to the note referred by Gertjan on: June 21, 2016, 04:55:46 am , implying that DHCP must be done by pfsense as CP works correctly.

It was suggested to use DHCP relay but I do not how could I use that for this situation.

jetberrocal

OH! Still does not work.

I turn dhcp off in the AD server and turn on dhcp on pfsense. The PC aquired the IP succesfully as can be seen on the dhcp leases in pfsense.

But chrome does not call the CP login page.

Derelict

Is the AD DHCP server in the same subnet as your clients? If not you will have to use DHCP relay to get there and put the proper scope in the DHCP Server.

What happens if you go to http://10.10.10.10/ in chrome?

My network is really simple.

My LAN is 192.168.56.x, 255.255.255.0
AD has static IP 192.168.56.10
pfsense has static IP 192.168.56.1
DHCP server sets:
from 192.168.56.100 to 192.168.56.254
DNS = 192.168.56.10
Gateway = 192.168.56.1

WAN is DHCP assigned by the Cable modem

Trying http://10.10.10.10 gives me "took too long to respond" error

Table 100 contains the IP of the Captive Portal NIC.

Ok.
and what are these setting on the device that you used to :
@jetberrocal:

Who is this IP :

---table(100)---
192.168.56.1/32 0

?
Table 1 and 2 contain the "logged in users" - so "192.168.56.100" has been logged in successfully.

The device I am using for testing is a Win 7 Pro attached to the AD, that is assign an IP by the DHCP. Since is only one the IP assigned is the first DHCP assign value which is 192.168.56.100.

The test device using Chrome sometimes shows the CP Login page and I can logging successfully. Thus the table shows in this occasion the device MACs.

BUT after successful login, the trigger page is shown, but no other page. The network is broken as if the login were unsuccessful but worst because the CP no longer is trigger. (I close the browser, and remove/delete the line from the CP status in Diagnostics)

I cant ping any Internet address not even resolve the addresses.

I thought this was because the DHCP server was in the AD and not the pfsense, but I turn off the dhcp in the AD and activated the dhcp in pfsense and still have the same bad behavior.

Consider this : if you address your browser to the right pace (the captive portal IP address) you should see the login page.
A DHCP server gives more as a IP address for a client-device.
It also hands over the gateway (and a DNS, etc), which should be pfSense, and not some other IP.

First the gateway is inaccessible, but a browser startup up will be 'captured' by the portal interface. Authentication will make the firewall in front of the portal transparent, and of you go …

What is the gateway that your server offers to its clients ?
What is the gateway your clients are using ?

Humm.
Can't find anything wrong.

When your "192.168.56.100" is logged in - you can check that using the pfSEnse GUI Captive portal Satuts page - or inspecting table '100' using the ipfw show …. test - the barrier "capive-portal-pfsense" will be inexistent for that device ("192.168.56.100") - it's like the captive portal has been shut down for this device.
So : my question is : if you shut down the portal function, does the 'internet' access work ?

jetberrocal

I turn off the zone, and the Internet access started to work.

jetberrocal

To clarify. The pfsense IP is 192.168.56.1/24, but CP table(100) is register with 192.168.56.1/32. I dont know why /32.

Gertjan

@jetberrocal:

To clarify. The pfsense IP is 192.168.56.1/24,

pfSense has an IP on it's LAN - it is 192.168.56.1 (or written as 192.168.56.1/32 ;) )

@jetberrocal:

but CP table(100) is register with 192.168.56.1/32. I dont know why /32.

It means : This IP only - because the mask is '32'

edit : change the IPv4 firewall rule : remove the source (LAN net) and make it "all"

jetberrocal

Why pfsense IP is written as 192.168.56.1/32 when the LAN Interface is setup as 192.168.56.1/24

I can't select /32 when setting the interface.

I only have the default firewall rules. You mean to change the IP4 default rule?
What would be the implication?

I still have CP failing to work normally.

I need CP with transparent Squid and squidguard, I need CP so squidguard can get the User name to select the group policy instead on general policy.

I am desperate, please help.

This seems a feature request to me.
I advise you to have a look over here Post a bounty

According to this threads what I want seems a posible thing:

https://forum.pfsense.org/index.php?topic=74309.0
https://forum.pfsense.org/index.php?topic=74572.0

Squid has CP as Authentication selection so this should work.

But if CP is not working obviously it can be done.

I just want to make CP work first. What I see is that it takes a genius to make CP work.

@jetberrocal:

..

I'm using pfSense because it has a Captive portal.
I'm using it for my work, an hotel.
It works perfectly for meany years now. Check it yourself : https://www.test-domaine.fr/munin/brit-hotel-fumel.net/pfsense.brit-hotel-fumel.net/portalusers.html

Btw : never used "transparent Squid and squidguard" - I do not know what that is, neither why I should use it.
I'm a fan of keeping things simple.

Btw2 : I'm working at a hotel …. so I can do many things, but being a "genius" isn't among them - neither are my clients ;)

jetberrocal

I am sure that CP works in thousands of installations, but in mine is broken. I need help to fix it.

Using CP with Squid and squidguard is a matter for other thread. I removed squid from my installed packages before asking for help to eliminate the complications for now.

But the problem persists and I dont know what to do. I already apply the last pfsense update.
