      Hi I am having the same issue, upgraded from 2.0.1 (i386) to 2.0.2 in the services tap captive portal appears down. Interestingly I use radius and openldap for the username and passwords on a separate computer. When a user types in a username and password they get an error saying that page could not be reached, but then if they close the browser and open it they have been authenticated by captive portal and all is working. I am also using esx 4, I use squid (as transparent proxy) and squidguard and a wpad file to auto configure the browser. It all worked fine before the upgrade.

            I updated (sync'd) again. Everything has remained stable over night.

              I did a gitsync the other day and that fixed the captive portal being stopped issue. What I've noticed since though is that clients have to either renew their IP or turn WiFi Off/On to be redirected to the captive portal after the 1 hour time out. DHCP default and maximum lease times are not set in the configuration so I'm presuming they are 720 seconds and 86400 seconds respectively, both definitely longer than the time out.

                    Hi everyone,

                    I confirm with the fix is working.

                    But i have some logs that i don't understand like :

                    lighttpd[34598]: (mod_fastcgi.c.2676) FastCGI-stderr: ALERT - ASCII-NUL chars not allowed within request variables - dropped variable 'redirurl' (attacker '172.16.1.37', file '/usr/local/captiveportal/index.php')

                    lighttpd[34598]: (mod_fastcgi.c.2676) FastCGI-stderr: ALERT - ASCII-NUL chars not allowed within request variables - dropped variable 'sessionkey' (attacker '172.16.1.141', file '/usr/local/captiveportal/index.php')

                    lighttpd[34598]: (connections.c.137) (warning) close: 73 Connection reset by peer

                    Best regards.
                    Myke.

                      Using 2.02 in a production environment so I am reluctant to do a gitsync. I may come in this weekend and give it a try.

                      Interesting that although under service status the captiveportal service says Stopped captive portal is running and users are being asked to login.

                        Hello.

                        I have the "same issue" Since I upgrade my installation, captive portal don't works as expected. I have had to disable it.

                        My problem is that the ip roules stop working suddenly.

                        f.e. my rule "both any->10.2.0.0/16" stop working and the only way to work around was enable certains IPs on the captive portal (so they have access to internet too, and i don't want this).

                        Thanks!

                        Now i'm gitsyncing.. I'll try after

                          Hi after gitsyncing and going to 2.0.3 I had a number of other issues, such as under heavy load the firewall blocking everything with nothing entered into the syslog. we have 800 captive portal users and everything was working well in 2.0.1 . I have reverted back to 2.0.1 . The main reason was due to the crashing and the fact that the web gui became really slow, and crashed alot. I run 2 other pfsense devices and I have not gone back to 2.0.2 on them as they do not use captive portal. On all the devices that I have upgraded i have found the performance of the webgiu gets much worse after the upgrade with me having to remove the status widget from the dashboard to make some small improvements.

                            Web GUI seems very fast with 2.02. Have not gitsynced yet. Is there a 2.0.3 release? I have not seen it.

                                he is right is there any workaround, a lot of error message coming out. Also Captive portal is not working.

                                  The latest 2.0.3 is stable from our testing.
                                  Can you try because at the time there were some changes being done.
                                  Now it is marked as stable on our side!

                                          That's just a warning because it tries to forward anything on tcp to port 80 which has been reduced only to tcp traffic on 2.1 version of pfSense.
                                          Since the client is trying an https://www.pfsense.org but the firewall redirection sends it to a simple HTTP talking webserver you get the warning.
