        /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.  :-\

/usr/local/sbin/usb_modeswitch usb_modeswitch -v 1a8d -p 2000 -M "5553424312345678000000000000061e000000000000000000000000000000" -2 "5553424312345679000000000000061b000000020000000000000000000000" -n 1 -W
sleep 5
/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!

                    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.

                    Steve

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

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

                          Hmm, yes you are close. I have to say that I have only played with this a little and mostly under Ubuntu and that was a few years ago!
                          My own modem turned out to be supported by u3g on FreeBSD so I didn't need usb_modeswitch.

                          Does your modem have an SD card slot?

                          It looks like it's doing it's thing. From the log you see it has removed the virtual cd drive and you can see it receives the '1' response it's looking for.

                          From memory the creation of a new serial port does not generate any log entries which is why I initially thought my modem wasn't working.

                          Check the contents of /dev.
                          There are two ways in which serial ports are represented by FreeBSD and both are shown just to confuse you. Here is the output from my box before I connect my modem:

                          
[2.0.1-RELEASE][root@pfsense.fire.box]/dev(2): ls
ad0        ata        cuau0      devctl     klog       mem        ptmx       stdout     ttyu1.lock urandom
ad0s1      bpf        cuau0.init devstat    kmem       nfslock    pts        ttyu0      ufs        usb
ad0s1a     bpf0       cuau0.lock fd         led        null       random     ttyu0.init ufsid      usbctl
ad0s2      console    cuau1      fido       md0        pci        speaker    ttyu0.lock ugen0.1    xpt0
ad0s2a     crypto     cuau1.init geom.ctl   md1        pf         stderr     ttyu1      ugen1.1    zero
ad0s3      ctty       cuau1.lock io         mdctl      ppi0       stdin      ttyu1.init ugen2.1

                          And after:

                          
[2.0.1-RELEASE][root@pfsense.fire.box]/dev(3): ls
ad0          console      cuaU0.2.init devstat      mdctl        pts          ttyU0.1.init ttyu1.lock   xpt0
ad0s1        crypto       cuaU0.2.lock fd           mem          random       ttyU0.1.lock ufs          zero
ad0s1a       ctty         cuau0        fido         nfslock      speaker      ttyU0.2      ufsid
ad0s2        cuaU0.0      cuau0.init   geom.ctl     null         stderr       ttyU0.2.init ugen0.1
ad0s2a       cuaU0.0.init cuau0.lock   io           pass0        stdin        ttyU0.2.lock ugen1.1
ad0s3        cuaU0.0.lock cuau1        klog         pass1        stdout       ttyu0        ugen2.1
ata          cuaU0.1      cuau1.init   kmem         pci          ttyU0.0      ttyu0.init   ugen2.2
bpf          cuaU0.1.init cuau1.lock   led          pf           ttyU0.0.init ttyu0.lock   urandom
bpf0         cuaU0.1.lock da0          md0          ppi0         ttyU0.0.lock ttyu1        usb
cd0          cuaU0.2      devctl       md1          ptmx         ttyU0.1      ttyu1.init   usbctl

                          cua and tty devices are all serial ports. Those with a capital 'U' in the name are USB connected serial ports. You can see that my modem add three serial ports.
