      Thanks for the quick replies. We're studying what the best way to fix it is. In the meanwhile, if you need to restart OpenVPN after performing changes to the config screen, issue:

      echo "" | php -q

          Yeah, same problem here… openvpn is not running when I run it from the command line:

          # /usr/local/sbin/openvpn --config /var/etc/openvpn_server0.conf

          I can't seem to find what is using 1194 when openvpn is not running.

            From a shell issue a sockstat command to see what processes are listening on what ports.

              *root     check_relo 326   11 udp4   :1194                :

              so something is wrong with check reload status… when i kill this process everything works fine!

                Eh, this doesn't make any sense.  check_reload_status doesn't even open a socket.

                  Yeah, I've got another whole mess attached apparently:

                  # sockstat | grep 1194
root     sleep      3078  10 udp4   *:1194                *:*

                    i try this many times… but when i try change openvpn settings, check_reload_status block port 1194. When i kill it everything work fine and i can change openvpn settings without any problem until next restart...
                    After restart, openvpn run ok until i try change some options...

                              At this point I am at a loss.  Will have to discuss it with the other devs.  We are all really confused on this one.

                                root    lighttpd  1785  10 tcp4  *:1194                :
                                root    check_relo 339  10 tcp4  *:1194                :

                                    The only thing you can do is to make your changes and save, click the disable box to disable tunnel and then restart pf, and when its up again, click box to enable tunnel again.

                                      Same problem here and at a friends system and at work, too… even switching to another port did not work (only for one day - using 1195 now) and the system at work... still no changes  :'(

                                        I have the same issue (and have had for a while now), the OpenVPN server tells me whatever port number I'm using is already in use.  I've tried with the latest snapshot (Jan 7/06), same issue.

                                          Known issue. It's covered in 3-4 other threads but there is no solution as of yet.

                                            I'm having the same problem with my server in UDP mode. TCP mode works perfectly for me. Looking at the listening server processes with "sockstat -l" reveals:

                                            _dhcp    dhclient  794  10 udp4  *:1194                :
                                            root    dhclient  697  10 udp4  *:1194                :

                                            Apparently, the dhclient process is listening on UDP port 1194 …  ???

                                            FYI, my box is connected at the WAN side through DHCP to my ISP. In the OpenVPN server, I enabled dynamic dns clients.
