        Ok. tried again with snapshot 20101024.

        Here is the /var/etc/mpd_wan.conf:

        startup:

        configure the console

        set console close

        configure the web server

        set web close

        default:
        pppclient:
        create bundle static wan
        set iface name ppp1
        set iface route default
        set iface disable on-demand
        set iface idle 0
        set iface enable tcpmssfix
        set iface up-script /usr/local/sbin/ppp-linkup
        set iface down-script /usr/local/sbin/ppp-linkdown
        set ipcp ranges 0.0.0.0/0 10.64.64.0/0
        set ipcp enable req-pri-dns
        set ipcp enable req-sec-dns
        #log -bund -ccp -chat -iface -ipcp -lcp -link

        create link static wan_link0 modem
        set link action bundle wan
        set link disable multilink
        set link keep-alive 10 60
        set link max-redial 0
        set link disable chap pap
        set link accept chap pap eap
        set link disable incoming
        set link mtu 1492
        set auth authname "wapuser1"
        set auth password wap
        set modem device /dev/cuaU0.2
        set modem script DialPeer
        set modem idle-script Ringback
        set modem watch -cd
        set modem var $DialPrefix "DT"
        set modem var $Telephone "*99#"
        set modem var $APN "isp.apn"
        set modem var $APNum "1"
        open

        I still get the "ppp: [wan] can't config [c]:: Invalid argument", this time I also got another variation "ppp: [wan] can't config [33]:: Invalid argument".

            This problem still exist in RC1 (i386-20110226-1429).

            I also noted that when trying to use two USB 3G modems only one connects, the other gets USB_ERR_TIMEOUT.

            RC1 is clearly not ready for production.

              I also have the same problem with my Huawei 3g module.

              Is there a way to set the PPP debug level to MAX?

                  Please read this post about the MPD binary.
                  Maybe some files are outdated?

                    This affects the new Huawei e398 LTE modem as well.

                    Relevant line reads:

                    ppp: [wan] can't config [1c]:: Invalid argument

                      OK, Problem solved!!

                      See http://sourceforge.net/projects/mpd/forums/forum/44693/topic/4516341

                      Changed NG_PPP_MAX_BANDWIDTH in ng_ppp.h kernel file to a much higer value. The big BPS number of the K4505 Huawei modem is confusing the bandwidth maximum.

                      
/* Max allowable link latency (miliseconds) and bandwidth (bytes/second/10) */
#define NG_PPP_MAX_LATENCY      1000            /* 1 second */
#define NG_PPP_MAX_BANDWIDTH    125000          /* 10 Mbits / second */

                      a MPD developer is changing the source of MPD5 now, so maybe update PFsense with the new MPD code in the future??

                        Imported the fix done on mpd5 sources in pfSense.

                          Does the Huawei E398 work with RC3 or what's the status? I'm having some trouble getting go grips with if it works or not. Some people are having trouble with usb_modeswitch and for some other it works.

                          Could someone enlighten me?

                            The e398 works with the RC3. I use it on a laptop based home router an it serves well. (Thanks to ermal for the commit and GrandmasterB for the info). You may have to set it to 4G only on a Win PC first as I am uncertain if Linux and FreeBSD can set that parameter or how it will behave if set to auto.

                            The only issues I encounter in experimenting occur - or so I think  for now - if other USB interfaces are activated. In my setup a reboot with an USB ethernet adapter and wireless adapter alongside the e398 - all with previously successfully assigned interfaces - saw an "interface mismatch" message and the interface assignment routine started. Removing and replacing the devices in some or other sequence saw the old assignments be picked up and the bootup completed. My impression is this is a usb-modeswitch issue with the e398 but more needs to be done to isolate what triggers it.
