      It doesnt do anything, the box continues its boot process as if no modem was plugged in. I see the modem details flash up on the console towards the end of the boot process but PPP has already initialised at this point (without seeing the modem) so i suspect it wont keep on attempting a dial out because as far it's concerned, no modem was detected at the time of initialisation, I hope that makes sense!

        Yes I see exactly what you mean.
        Would probably be best to use an rc script then.
        This is just a guess but perhaps:

        
#!/bin/sh
/usr/local/sbin/usb_modeswitch -c yourmodem.txt
sleep 5
/etc/rc.reload_interfaces

        Try issuing a /etc/rc.reload_interfaces and see if it finds the modem and connects.

          I had just finished creating a similar script and was looking for a command that would restart PPP, the reload_interfaces seems to do the trick nicely, thank you.

              If it's an RC script, as I detailed above, put it in /usr/local/etc/rc.d and it will run at boot.

                  Yes Jamesc experienced that problem above.
                  Doesn't it redial when you reload the interfaces in the script?

                  Steve

                      problem occurs: persistent disconnections..i cant make my modem to hold for an hour or so..my ppp connection disconnects  every 10 seconds..i try to use my 3g modem directly with my laptop but never had a connection hangup..

                        Is it exactly 10 seconds every time? This might indicate some sort of ppp error. Or more random?
                        What do you see in the logs? Does it do this if you setup the connection manually instead of using the script?
                        Have you set the PPP session to be 'always on' (idle timeout = 0, which is the default setting)

                        using rc.reload_interfaces seemed a bit crude when I suggested it earlier and it still does. It maybe that it is causing some other undesired consequence. It would be much better to simply reload WAN or indeed just have it redial. Sadly I'm not sufficiently familiar with the code to suggest anything better.  :(

                        Steve

                        Edit: rc.linkup WAN up (or should that be 'up WAN') perhaps?  :-\ Complete guesswork!

                            /etc/rc.reload_interfaces in my script causes my 3g ppp connection to restart every 10-20 secs..

                              Can you show us your script?
                              It should only be run once at boot, I can't see how it could possibly effect the ppp cycling time.  :-\

/etc/rc.reload_interfaces

                                removing reload interfaces makes my 3g ppp connection stable..is there a place where my script will run first then ppp dials in?or to restart ppp connection after my script run?
                                i can easily do this with openwrt/ddwrt but i want to try pfsense..

                                  The code in /usr/local/etc.rc.d should only be run once as far as I know.
                                  You could try calling the script using shellcmd or earlyshellcmd instead:
                                  http://doc.pfsense.org/index.php/Executing_commands_at_boot_time

                                    thanks,,same thing it doesnt auto connect on boot even if i edit my xml with earlyshellcmd or shellcmd..
                                    on openwrt,,i usually put my script in /etc/rc.local and run a cron job with a watchdog scripts,,it automatically restart my 3g interface when ppp hangs up.hope i can do same thing on pfsense.am total noob with pfsense thats why im still catching up with it..

                                      Hello,

                                      I'd really like to get this feature working on my pfSense box.

                                      I read through this thread 3 times but, I don't see how to go about actually installing the port or using one of your scripts.

                                      If you have a minute or two, can you just throw together a how-to so I can take the necessary steps to get this to work?  I'd really appreciate it!

                                      Thank you!

                                      -th3r3isnospoon

                                        Ok, this may have to be multipart as I'm pushed for time!  ::)

                                        First check the usb-modeswitch forum/website to see if your modem is supported at all:
                                        http://www.draisberghof.de/usb_modeswitch/
                                        Note down any relevant switching code that other users may have posted if it's not included as standard in device_reference.txt:
                                        http://www.draisberghof.de/usb_modeswitch/device_reference.txt

                                        Install the FreeBSD package in pfSense. This will vary depending on your pfSense version.
                                        For 2.0.X NanoBSD:

                                        
/etc/rc.conf_mount_rw
pkg_add -r ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8-stable/Latest/usb_modeswitch.tbz
/etc/rc.conf_mount_ro

                                        For 2.0.X full install:

                                        
pkg_add -r ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8-stable/Latest/usb_modeswitch.tbz

                                        Now depending on what the required code for your modem is you can either just enter it at the command line directly, e.g.:

                                        
/usr/local/sbin/usb_modeswitch usb_modeswitch -v 1a8d -p 2000 -M "5553424312345678000000000000061e000000000000000000000000000000" -2 "5553424312345679000000000000061b000000020000000000000000000000" -n 1 -W

                                        or call a file containing the appropriate section from device_reference.txt (or some custom code), e.g.:

                                        /usr/local/sbin/usb_modeswitch -c yourmodem.txt

                                        You can run it with -h to list the command line options:

                                        /usr/local/sbin/usb_modeswitch -h

                                        If you get it right usb_modeswitch will report success and you will see some lines in the pfSense log showing devices removed and attached.

                                        If you have found the code to correctly switch your modem you can put a script file in /usr/local/etc/rc.d.
                                        Call it whateveryouwant.sh:

                                        
#!/bin/sh
/usr/local/sbin/usb_modeswitch -c yourmodem.txt
sleep 5
/etc/rc.reload_interfaces

                                        I am still of the opinion that /etc/rc.reload_interfaces is probably not the correct way to get the modem running, it seems too crude, but it worked for jamesc.

                                          You sir are a gentleman and scholar.  I really appreciate this.

                                          I will try this out, this evening and report back.

                                          THANK YOU!

                                            When I go to see if I can add a PPP interface, still none are listed.  What should I change in order to make it work?
                                            I'm so close, I can feel it!!

                                            Thank you!
