  Hi, Most spread sheets, Excel, to name just one, if not all, can import CSV files. Up to you to do a minimal manual formatting, or use some scripting to make a 'nicer' format.

  try removing all the MAC addresses first and then adding them back to the list after you had changed the up/down speed limits. My experience has been that if those MAC addresses have been added before you made the changes they will keep the old settings.

  Well, the advantage of open source is : you can do what you want, so there are many ways. Something like this - it's executed every 5 minutes by a Munin client : <?php require_once("/etc/inc/util.inc"); require_once("/etc/inc/functions.inc"); require_once("/etc/inc/captiveportal.inc"); /* Read in captive portal db */ /* Determine number of logged in users for all zones */ $count_cpusers = 0; /* Is portal activated ? */ if (is_array($config['captiveportal'])) /* For every zone, do */ foreach ($config['captiveportal'] as $cpkey => $cp) /* Sanity check */ if (is_array($config['captiveportal'][$cpkey])) /* Is zone enabled ? */ if (array_key_exists('enable', $config['captiveportal'][$cpkey])) { $cpzone = $cpkey; /* Zone selected -> count users and add */ $count_cpusers += count(captiveportal_read_db()); } echo $count_cpusers; ?> and the info retrieved, the number of logged in portal users - is used to generate this. The code above is what ne would call a Munin plugin. Many others exist.

  Hello @yanqian, I could not configure a Radius server in PfSense "Authentication Servers". I followed several tutorials and Windows NPS event log was returning succesfull authentication attempts, but I could not figure out why didn't PfSense was not getting them. Finally I had success using LDAP instead of Radius in PfSense "Authentication server" to connect to Windows Active Directory. With LDAP It worked at first attempt.

  @mohkhalifa Well, I found 2 threads about Microsoft NPS posted by you in CaptivePortal category, and I am glad that you figured out how to use Microsoft NPS as radius server for pfSense authentication. It's better that you can take some time to share your experience in your own thread, It will help me and others who may got the same issue.

  edit : see below - bottom - 0.15.7_17 includes this edit. See here https://forum.netgate.com/topic/139132/need-help-on-max-daily-session-attribute?_=1600411248200 pastebin.com (do not post it here) your /usr/local/pkg/freeradius.inc file. Just search sql1 {$varsqlconf2authorize} } and add there : dailycounter monthlycounter noresetcounter expire_on_login just before the line with EOD; Save, stop FreeRadius, start FreeRadius and again, keep in mind settings are thrown away if you upgrade the FreeRadius package. But re editing (if needed) is so easy .... edit : I just upgraded FreeRadius to 0.15.7_17 and this edit (patch) is now included.

  @Ahabash you are already able to do that. Using DNS logs+ captive portal logs, you can check which user accessed which website. If you are looking for the precise URL (and not just domains) : please be aware that most of websites are in HTTPS nowadays (which mean : you can't).

  Hi, FreeRadius is better integrated these days, and can be installed as a pfSense package. You'll be needing a MySQL (MariaDB) SQL server. This one doesn't (should not) run on pfSense. If you're capable of running and maintaining** these these two, you're pretty close to redoing a bit the code used in the project, as html, ccs and PHP. These 3 had their rocket science status removed in the late nineties. The problem with big addons is .... they only work for a couple of months. As soon as pfSense updates, chances are that something breaks. The author should solve the issue as soon as possible. This means he should be using a portal himself. Which means he already knows that an animal called "RGBD" really exist. When you run a captive portal, you should apply this rule " keep it simple ". Not doing so means : Very soon, you will not be doing what you are doing right now. pfSense is a security device, not some nicely coloured gadget. If updates exist, you install them. If the installed code is personalized which this kind of addons, admins tend to stop updating. And that's another way of going out of business with a lot of buzz. ** FreeRadius and MySQL are not "set them and forget them" type of services. Btw : I guess you do understand that the nearly identical question "Can I use the user's Facebook account to login in into my portal ?" vanished. Some English company did woke up a lot of people. And Facebook changes it's API every week or so. edit : almost forgot : this method is still allowed !

  Hi, @emad said in Nginx "404 Not Found" Error after POST action to "$PORTAL_ACTION%2quot;: So, do I miss knowledge with CP behavior or should I modify something? You might as well check (== read and understand what happens when and why etc) this file /usr/local/captiveportal/index.php It's the file that's get 'executed' when a users is redirected that the portal login interface. Read that file carefully - and also check this one : /etc/inc/captiveportal.inc which contains all the functions. For instance, you'll find why/where/when a string like $PORTAL_ACTION$ is replaced by the correct URL before getting send to the client. Throwing $PORTAL_ACTION$ at the client's web browser who throws it back to the captive portal web server will produce 404 errors.

  @ghassen said in Allowed-hostnames not working.: I have disabled both the DNS Resolver and Forworder if that's what you mean. And then how is client on your captive portal suppose to look up www.google.com then? Do you hand them external dns that you allow through captive portal? @Gertjan stated - working dns is a MUST for captive portal to function. Where does pfsense point for dns? When it finds the ip for www.google.com better hope it matches what the client finds when it does query.. Pointing to different dns can exacerbate problems with mismatch of IPs..

  @Gertjan said in Newbie need help to merge pfSense Captive Portal with old Linksys WRT54GL hotspot feature: @ha11oga11o said in Newbie need help to merge pfSense Captive Portal with old Linksys WRT54GL hotspot feature: Also on router i have WiFiDog and Chillispot. But my problem is that i dont know what to use as redirect page to pfSense machine. The "page to redirect" etc does not concern pfSense at all. You'll be using the hotspot's facilities of the AP, there is nothing to be done on pfSense. If you set up the AP on the WAN side of pfSense, the question is even less relevant, as the traffic isn't seen by pfSense. For help about the hotspot's (DDWRT) : see their forum. I don't know what Chillispot is, neither Wifidog. You can also transform your WRT54GL as a simple AP - I'm using several of these Linksys/Cisco routers, with the DDWRT firmware - and activate the portal on pfSense. In that case, I strongly advise you to use a dedicated interface on pfSense (a third interface) for the portal, leaving the LAN for trusted devices - and the OPT1 interface for the non trusted devices, as are portal users by default. I you choose to use pfSense for the portal management, start by looking up the Youtube site on the Internet. Then locate the Netgate channel, and see (several times) the Captive portal and DNS videos. When done, a portal can be set up in less then 10 minutes. Remember : keep it simple at first. Well, you definitely pointed me right way. I do want that pfSense is handling portal and WiFi just to be "radio" device for that. Thank you.

  Dear @soheil-amiri No need to use freeradius in pfSense. Just deploy MS Radius Server and integrate it with pfSense and send your own attributes and that's the best way I'm using.

  There might be a 'pfSense' limit, but you will not find it out. Handling a voucher roll with thousands voucher needs a special way to handle used and unused vouchers. Will that be you using a print out and a pencil ? Some excel sheet that you maintain by hand ? When things get messy, it might be easier to remove the roll, ans start using another one. Btw : the bit numbers determine the seed, so there will be a limit for sure.

  The ipfw firewall rules, put in place when the captive portal is activated, start with some rules letting through DHCP traffic. It's part of the default rule set. When a device is hooked up, can you see DHCP traffic (DHCPDISCOVER) in the pfSense DHCP logs ? If not, NIC is bad, cable is bad, or some switch device between user and pfSense. Btw : you should keep LAN for admin purposes, and use a second interface - OPT1 - for the portal. If remote admining is needed, use OpenVPN @wakasavan said in DHCP Stop Working when captive Portal is enabled: As long as captive portal enabled no Internet at all. That's what a portal should be doing. @wakasavan said in DHCP Stop Working when captive Portal is enabled: I repair the the firewall but there is no issue there What do you man ? You repaired something that wasn't broken ? @wakasavan said in DHCP Stop Working when captive Portal is enabled: Firewall can be accessed via WAN link but from local interfaced it is not working. If a portal is activated on that LAN, then,except for obtaining an IP, nothing should work. Exception : DNS requests ! Check that. But ok, if the device can't get an IP, all will be down. @wakasavan said in DHCP Stop Working when captive Portal is enabled: There was a power outage for a long time The power of pfSense was shut down using the way it should ? Do you use a UPS ? The file system is clean ? ( see very recent Netgate video on Youtube).
