Is clear os 5.1 compatible with samsung 3G UMTS modem and able to use it as wan interface and use it as failover/backup even loadbalancer for my existing adsl connection? Currently I'm using pfsense as my firewall/router/proxy problem and I don't have any problems with it except it does not support my 3G modem as failover/loadbalancer.

My laptop has ubuntu 9.10 installed and the samsung 3G usb modem works just fine. Since clear os also based on linux I guess there is high chance that clear os should be able to detect it too. If somebody can confirm it I'm migrating to clear os straight away!

    I hope this can eventually be feasible with kernel upgrades, etc. COS 6 perhaps???

    I've used the Cradlepoint CBA250 with excellent results. But it is an additional cost.

    Scumback and dope,

    I guess you are right. COS 5.2 does not claim to support USB 3G - and it does not seem to do so with simple hacking anymore - 5.1 did.

    My answer was to move the dongle to a Windows Machine and simply use Windows internt sharing as an interime solution until we get a cable based connection and I can reinstate my COS server. Your respective solutions seems equally good - except that in the case of zeroshell, I would seriously miss the mail server capability, so that is not a long term option for me.

    Sad but true.

    i was using a e220, using 5.1 with an updated kernel ,the hardware side seem to be all good as it sees the device and dials out and connects when i wvdail from shell.

    but i noticed it give a weird dns,
    11,12,13,14
    no matter what setting i used, and the webif would just show not connected.

    doesnt matter anyway i moved to zeroshell, where everything was plug and play with my modem also has a ping feature to test the connection for automatic failover.

    I went out and bought a Netcomm 3G18Wn - a wireless/ADSL/3G router which will do the job nicely for me. The router itself falls back to the 3G stick when the ADSL goes down. It would be nice for COS to do it, but it wasn't worth the hours in the end.

    Did you check that the ttyUSB* are created? I recently noticed that COS 5.2 does not seem to do this, even after coorecting the UDEV problem mentioned in my Howto mail on page 2 (I think) of this thread. I do not know why and did not have the time to investigate in detail.

    So, in short, what dongle are you using, what COS version are you using and did you faithfully follow the howto?

    ive got a problem,
    ppp0 is displying "offline" "not in use" in multiwan
    i have no idea why it doesnt work because it is obtaining my external IP address from my ISP(static) and it looks like its connected as the modem is light is constantly lit.

    also when i type wvdial,it looks like its connects it obtains all the required info,everything looks like is connected but its not as i cant connect to it externally.

    any ideas?

    Edit the /etc/firewall/ file to include ppp0 in the EXTIF= line, eg: EXTIF="eth0 ppp0"

    Scumback,

    Review the entire howto. it is towards the bottom af page 2 of this thread. There are one or two other tricks to be mastered before it works.

    to make this very simple add a second wan nic and a cradle point http://www.amazon.com/Cradlepoint-CTR-350-Cellular-Travel-Router/dp/B001FWH0A0
    that will auto dial any usb 3g and just turn off the wireless and your set. it will dish out the wan its own ip and good to go. as far and the dns unless you locked by isp use googles dns 8.8.8.8 and you will see improved dns query's.


    Unfortunately :
    Currently, item can be shipped only within the U.S.


    I can probably source something similar locally, though it'll be cheaper to use an old Windows laptop, share the network connection and forward all the ports to the linux box. Either way it feels like a failure since the USB stick ought to work.
