I can't get Captive Portal login page in any browser else Firefox
-
I am currently in testing. I have a Virtual network of DC and PC in LAN side and pfsense VM with fixed IP on LAN side and WAN DHCP assigned IP. CP listens in LAN interface. DC (Windows 2003 server) has Firefox, Chrome, and IE 8.0 browsers, PC (Win 7) has Chrome and IE 8.0 browsers. There are no wifi clients.
-
Notice that now, when CP Login is shown successfully, after doing the Login the PC fails to ping external sites (www.google.com) like being blocked. I checked the CP status and the MAC address of the PC is registered successfully and active. So it should not be blocked.

Your portal interface is on an interface - probably named initially OPTx.
Please list the firewall rules (see GUI this time !) and gives us YOUR rules for this interface.
Remember : by default, LAN has ONE rule : let all pass. By default, all other interfacse have ONE hidden rule (the list will be empty) : BLOCK ALL.
Do you let in ICMP ? ("in" because it's from the point of view of the interface). -
I do not have OPT interfaces, only LAN and WAN. I think ICMP is allowed. When I have CP off I can ping from inside to outside successfully. With CP on I can ping the pfsense LAN IP.
-
I notice that I can ping the site which triggered the CP Login not other.
Example.
I Open browser (Chrome). The home page fails to load and does not trigger the CP Login.
I write in the address bar a http address (http://www.jetsystemservices.com). The CP Login is triggered.
I login successfully and the site is shown. (External links in the site fails, youtube links)
I go the command prompt in the browser computer and I can ping the www.jetsystemservices.com site. But I cannot ping other address.It is like CP only allows one address at a time instead of opening all internet.
-
….
I Open browser (Chrome). The home page fails to load and does not trigger the CP Login.Is this the locally build page that doesn't need any 'internet' access -
or
is this a page like http://www.google.com (and NOT https://www.google.com !!! ) that comes from the net ?….
I write in the address bar a http address (http://www.jetsystemservices.com). The CP Login is triggered.Great !
….I login successfully and the site is shown. (External links in the site fails, youtube links)
at that moment, go here https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting
and list us your ipfw rules and tables (what IN these tables)also, at that moment:
open command prompt
and
ping www.yutoube.comThe URL is resolved ?
The ping replies ? (youtube.com might decide not to reply, that's ok) -
The home page is http://www.google.com
Ping to www.youtube.com does not resolve.

Now I think got worst.
I reinstall pfsense 2.3.1 amd64 from cero, even format the HD to make sure no files remained. Did not install any package. I set the LAN IP static, WAN IP takes IP from Cable modem DHCP. I turn off DHCP on LAN interface as the LAN side takes the IPs from the Windows Domain DHCP server.
Added CP zone, with Local Authentication. HTTPS Login unchecked. Added the pfsense IP at Allowed IP Addresses.
The Win7 computer access internet as if CP is turn off, is not blocked.

STOP.
While you set up your portal settings, read the foot note.https://forum.pfsense.org/index.php?topic=111737.msg632639#msg632639
( => case solved ;) )

OK. I though that there was a posible work around.
Not being the case, for my needs CP in pfsense is not a viable solution. In my case as many others, DHCP and primary DNS must be kept on the Windows Domain Controller.

DHCP Relay (and keeping DNS to DC) is not an option?

DHCP Relay (and keeping DNS to DC) is not an option?
How will I use DHCP Relay?
My DHCP (DC/DNS) server IP is 192.168.56.10 (static, 255.255.255.0)
My pfsense IP is 192.168.56.1 (static, 255.255.255.0) in LAN side, WAN is DHCP assign from cable modem. I do not have any other interface. -
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.
-
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.
-
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 = 192.168.56.1WAN 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.
My network is really simple.
My LAN is 192.168.56.x, 255.255.255.0

and what are these setting on the device that you used to :

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.
