[9.107] Netcomm AirCard 320U

frank1985au over 10 years ago

Hi all

I run Sophos UTM 9.107 on a J&W D2500GT motherboard with 2GB RAM and 320gb HDD. My current internet connection is 1.5Mbit ADSL1 (all I can get, I've got 5km of copper between me and the exchange and yet people two doors down can get ADSL2+ from the RIM near the shops - many angry, so rage - seriously, stop laughing, it's not funny when you're on this end) so my boss gave me a Sierra Wirele-- err, Netcomm AirCard 320U USB LTE modem and while it works great on the Netcomm 3G41WT router, I would much prefer to use it on my Sophos UTM firewall. Only problem is, I can't get the damn thing to connect.

This is what appears in the logs:

I've tried turning APN autoselect on - it just turns it off again.

Any ideas?

New update - I found out why it's not connecting.  The profile was activated in a previous attempt which stopped the modem from dialling.

As soon as I deactivated the profile, it dialled fine.  The connection lasted for all of three minutes before it would drop out and trash everything I've done.

I think this is the work of udev - it's probably restoring the devices to their former nodes.  Unfortunately the Linux community on FreeNode has been very unhelpful, claiming that what I'm doing makes no sense and that I should contact Sophos support.  Without a support contract, that's impossible.

I'm Googling like a madman, and I've tried a few permutations of rules that should match the devices, but so far nothing's working.  It almost seems like the device is resetting from the look of the logs below.

On a hunch, I fired up udevadm monitor to see what was going on, and got the following:

The longest I've managed to keep a connection going was 3 minutes. I've yet to establish a timeline as to how often this happens, or if it's a reaction to what I'm doing.

For what it's worth, here's the current udev rules:

fuka:/dev # cat /etc/udev/rules.d/72-sierra-dev-nodes.rules

KERNEL=="ttyUSB2", SUBSYSTEM=="tty", NAME=="DNU-ttyUSB2"

KERNEL=="ttyUSB3", SUBSYSTEM=="tty", NAME=="ttyUSB2"

Any insight at all would be most helpful.

That happened when it successfully connected. Then, 16 seconds later:

Ok, an update to my wild adventures.

It seems that LTE uses a new method called Direct IP for connecting. PPP support still exists, but it no longer uses /dev/ttyUSB2 and is limited to ~25mbps (26mbps by my testing).

I have successfully set up Direct IP on another device and have shared my findings with the UTM team - please go and vote on the feature here: Direct IP support for Netgear AirCard 320U and other LTE modems

Hi Frank,
I have voted for your suggestion. Thank you for posting your findings.

What did you patch on the UTM to get the aircard to work?

I went into the shell and renamed ttyUSB3 to ttyUSB2 and vice versa. This only worked for 5 minutes before udev realised what was going on and put everything back.

I'm currently trialling SmoothWall. It doesn't support Direct IP either, but it's open source, so I can change it to suit my needs.

... is what I would say if I could get it to install.  Sadly, when I went to install the latest 3.1 RC, it stopped dead after installing all files.  Frak.  And this was after 3.1RC3 installed fine - but of course the sierra module was missing, so while I had wwan0 in ifconfig, I didn't have the ttyUSB* device files to actually activate the service.  Curses.

Now, I'm currently running through the latest Linux From Scratch to build my own system.  Kinda sad, huh?

Hi Frank,
I have tried a couple boxes to provide an interface to the UTM, first was a netgear, not compatible.
Currently in Wagga wandering around, a bit bored and went shopping (wife is here for the week at a millinery forum), discovered a nice little d-link box.

The d-link dir-506L talks/functions in many roles. The default firmware doesn't allow usb and ethernet connectivity simultaneously, but if you upgrade it to v15 you get wireless and ethernet all talking to the USB 4G card which is what I am using at the moment.

When I return home, I will be setting this little box up as fail over in place of the USB interface which means another ethernet connection. Bring on the latest v9.2 kernel with the new intel NIC drivers. Or at least I now have a means of travelling with the portable UTM again.

Not necessarily. If you have a smart enough switch, you can use VLANs. I had a dog of a time finding a PCI 10/100 card that would work on my motherboard, so instead I set up a VLAN and used that. Yes, Sophos UTM will let you route via a VLAN. Note that you will have to VLAN everything once you do this - and have your switch set up ahead of time, then change ports on the UTM cable once you set it up. It's a lousy job trying to get into the UTM's web interface once the VLANs are set up on the UTM but not the switch.

Sorry, only just occurred to me what you were going to do.
