Default CP not working if enable

sujyo1 · Sep 2, 2016, 7:44 AM

If I turn on CP no internet. If I keep turn off CP internet working fine. No cp page open, No redirection, even on default cp. If I enter http://10.10.10.1:8002 no page & time out. Using DNS Resolver with default setting.
Here my pf settings.
WAN is on ISP static, 2 ISP DNS + 8.8.8.8 are set in general setting with ISP Defaut GW.
CP turn on on OPT1 (HOTSPOT) 10.10.10.0/24 DHCP enable. I try on pf 2.2.6 and new pf 2.3.2 no luck. CP working fine on other 2.2.4 Boxes. I am trying to move working CP page from pf 2.2.4 to 2.2.6 & 2.3

2.2.6-RELEASE (amd64)
built on Mon Dec 21 14:50:08 CST 2015
FreeBSD 10.1-RELEASE-p25

Firewall rules on OPT1

@sujyo1:

Any one can help?

Yes ;)

Remove all rules on OPT1, and place a simple 'allow all from all'.
Then test.

Also, visit https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting and tell us what are your 'ipfw' rules and tables.

To rule out any AP 'problemes', use a direct cable connexion from OPT1 to a hardwired switch to a test PC (what is the IP - Gateway, DNS, etc that this device got (DHCP !) from pfSEnse)

( Any references to IPv6 are 'useless' because your OPT1 (CP) can't handle IPv6 anyway )

Thanks for reply…

After try 3 days I went back to 2.2.6 still as is..
Here what I did...

I did disable dns resolver & enable dns forwarder with default settings.
Also added list of ISP/google DNS Servers in OPT' DHCP Server's DNS list
Added ISP/google dns IPs to CP pass IP list & in OPT1 FW pass rules
Copy old working CP page from 2.2.4 to this box. also try Default CP Page but no luck
In this hotel's box CP is OFF and all guest online as of now.

I saw this image :
Dashboard.JPG

The captive portal isn't listed as a running service - so its normal that it doesn't work.
No IPv4 on your internal interfaces - and know that the portal is IPv4 only …....

Btw read https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting again.
No need to copy the explaination of ipfw - we all have this when ipfw doesn't understand its parameters.

I have this :

[2.3.2-RELEASE][admin@pfsense.brit-hotel-fumel.net]/root: ipfw zone list
Currently defined contexts and their members:
2: sis0,

So, my zoner 'number' is "2" - my captive portal is running on interface "sis0" - which is correct for me, of course, because I have the captive portal running on the interface called "sis0".

Now, it gets interresting :

Btw : These 'ipfw' rules have nothing to do with the Captive Portal Firewall rules in the GUI.

Your ipfw rules are look fine to me.

Can you list what's in the "table(100)" ?
(normally, its the IP of your HOSPOT interface.)

Use:

ipfw -x 2 table all list

You have a switch with an IPv4 ??

Can you confirm that connected devices became an IP from pfSEnse (DHCP server running on interface HOSPOT) ? And the gateway (== IP interface HOSPOT), - DNS ?

Can your devices resolve domaine names ? (aka : DNS works) this even when you are NOT authenticated to the portal.

Normal that your LAN is down ?

Here what I did today... Make sure all interface's IPV6 set to none then remove IPV6 & keep IPV4 in all HOTSPOT firewall rules. then turn on CP & run this commend It show...its looks like few clients went through CP :)!! can see some are still struggling including switch(10.10.10.2) eventhough its mac is in cp pass list!

All APs set to static (IPV4 as above) GW 10.10.10.1, DNS 10.10.10.1

Can you confirm that connected devices became an IP from pfSEnse (DHCP server running on interface HOSPOT) ? And the gateway (== IP interface HOSPOT), - DNS ?

Yes device receive IP 10.10.10.0/24 GW 10.10.10.1, and 4 dns servers....

Can your devices resolve domaine names ? (aka : DNS works) this even when you are NOT authenticated to the portal.

Yes all clients can go online if CP is OFF, As soon as I turn on CP all are droping...then I manually xcle their DHCP leases and force them to get dhcp again so CP can show up...

Do you need THIS switch ? Why is it managed ?
If you change it for the time being for a dumb 10 $ switch.
A switch with an IP (MAC ??) (just trying to eliminate things that are off-standard)

You have a switch with an IPv4 ??
*Switch is Engenius EWS5912FP (managed L2 with wireless controller) set to static IPv4 10.10.10.2 then 7 APs- 10.10.10.3 to 10.10.10.9
All APs set to static (IPV4 as above) GW 10.10.10.1, DNS 10.10.10.1

Can you confirm that connected devices became an IP from pfSEnse (DHCP server running on interface HOSPOT) ? And the gateway (== IP interface HOSPOT), - DNS ?

Yes device receive IP 10.10.10.0/24 GW 10.10.10.1, and 4 dns servers....

Ok for all this.
Look fine and normal.
Remember : https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting

Section : Captive portal not redirecting
If clients are not being redirected to the portal page when attempting to browse on an interface with captive portal enabled, it's most always one of the following causes.

DNS resolution not functioning - the clients on the captive portal interface must either be using the DNS forwarder on pfSense, on the IP of the interface where the client resides (which is the default configuration), or if using some other IP for DNS, it must be an allowed IP entry. If DNS fails, the browser never issues the HTTP request, hence it cannot be intercepted and redirected.
Firewall rules on the captive portal interface do not allow the initial HTTP request - if the user is trying to browse to google.com, but HTTP connections are not allowed to google.com, the HTTP request will be blocked and hence cannot be redirected. Under Firewall > Rules, on the interface where captive portal is enabled, the traffic to be redirected must be allowed to pass. This is most commonly HTTP to any destination.
The client has an HTTPS home page - The request must be to an HTTP site in order for the portal to redirect the client.

@sujyo1:

Can your devices resolve domaine names ? (aka : DNS works) this even when you are NOT authenticated to the portal.

Yes all clients can go online if CP is OFF, As soon as I turn on CP all are droping…then I manually xcle their DHCP leases and force them to get dhcp again so CP can show up...

Note : An ISP normally hands over some of its own DNS. I never ever added extra ones like the "8.8.8.8" (why should I give Google the sites that I'm using ?). Why adding them ?
I use the default "DNS resolver" - not the "forwarder" (although it should work).

When the CP is being shut down (and GUI Firewall rules permit communication) all devices should have a 'internet connection'.
As soon as you put on the CP - and you connect a device to your Wifi - or you cable it up, you can not communicate anymore (normal, you should use a browser, visit a http://… site) and then authenticate.
BUT :
Running a
ping www.google.com
should always resolve "www.google.com" to an IP …. (this proves that DNS resolution IS working). See point 3 listed under "Section : Captive portal not redirecting".
Don't use always www.google.com to test - use an URL that IS NOT in your local (devices) DNS cache !!! (or flush your cache -> PC => ipconfig /flushdns !!!)

So, if a device is not getting redirected :
Check 1) what URL are you suing to start ? https ? then no go.
Check 2 : ping to www.whatever.tld resolve the URL to an IP ? (no ICMP replies, that is normal) If no then DNS troubles.

If DNS is working, a browser on a connected device obtains an IPv4 - et troughs out a "http GET" and that one request will be captured by this rule :
65532 0 0 fwd 127.0.0.1,8002 tcp from any to any dst-port 80 in
=> read : any communication coming in on port 80 (so : https => YOU LOOSE) will be redicted to 127.0.0.1 port 8002.
and that"s where the Captive Portal web server will reply with the captive portal login page …...
WHEN authentication succeeds, the client's device IP and MAC will be added to table 3 and 4.

As you already saw when listing your ipfw rules, two devices were listed in these tables, so they managed to login.

Of courses, after login, the "Captive Portal" firewall rules (ipfw !) become transparent - now are used the other, GUI firewall rules - they still / will apply.

My ISP hasn't ANY IPv6 capabilities.
But, I'm using https://ipv6.he.net/ - I have a free account there, and pfSense WAN and my entire LAN is using IPv6 (DHCP6) - all my devices on LAN are IPv4 and IPv6 connected.
But, the pfSense Captive Portal isn't IPv6 ready at all.
…. but look again at the ipfw firwall rules ( using https://en.wikipedia.org/wiki/EtherType )
65301 24 888 allow ip from any to any layer2 mac-type 0x0806,0x8035
=> ARP et RASP passes through.

65302 0 0 allow ip from any to any layer2 mac-type 0x888e,0x88c7
=> EAP ET PBB passes through

65303 0 0 allow ip from any to any layer2 mac-type 0x8863,0x8864
=> PPPoE passes through

65307 0 0 deny ip from any to any layer2 not mac-type 0x0800,0x86dd
=> IPv4 and IPv6 passes through ( !)

What a detail explanation abt CP!! Gertjan your are genious!! A BIG THANK YOU !!
I keep CP open for 5 hrs yesterday. only few guest able to log in others keep trying. I think there are DNS problem exist some where. or client's devices already running other apps, browsers etc in back ground preventing cp to open & redirect on their devices as you explain above
Q: Is http become auto https hotel's redirected website can causing this problem? As CP basic rule the redirect page must be a http site. So in CP page I put http://www.website.com not https. bcs when I go to hotel's http site its change to https automatic on my computer browser.

Do you need THIS switch ? Why is it managed?
If you change it for the time being for a dumb 10 $ switch.
A switch with an IP (MAC ??) (just trying to eliminate things that are off-standard)
*I keep this switch for remote tech support access so they don't have to mess with pf.

Read this https://forum.pfsense.org/index.php?topic=116386.msg645311#msg645311 to understand why nearly all devices today do present a login page to the visitor.
If they don't, they are NOT "portal aware" ….. (and should be updated or recycled ;) )

Btw : No, intercepting a direct, initial "https" GET and hoping that the portal login shows up is like hoping 'a man in the middle' interacts with your connection when you visit your bank account on the net. Don't ask for it - you won't want this .... ;)

Try to make a new user with full access to this page like SuperUser grant all access to this user.
then enable your captive portal.
open web browser and go to address bar and type the pfsense ip with 8000 port. e.g. http://192.168.1.1:8000
login page will popup then use the new username & password that you created lately like the superuser.
then done.
Internet can pass tru your PC now.
