Scripting the behaviour of Status --> Interfaces --> DHCP renew button

stephenw10 · Nov 18, 2018, 11:41 PM

I expect it to run that the dhcpclient when the shows as up. That's what the behaviour would be if it was a USB Ethernet device and you connected the cable. Or any Ethernet interface for that matter.

You might be able to do it using /etc/rc.linkup start wan but you would need to make that conditional. You wouldn't want that running every minute, it does a lot of things. One of them is running the dhcp client though.

Another issue you will hit here is that if the modem is unplugged or not in ndis mode for some reason pfSense will not boot fully if ue0 is not detected. It will wait at the interfaces assign screen on the console. That's the main reason why ppp is currently preferred for direct conected modems and an external Ethernet connected device is the best option.

Did you found any solution for this??Im deploying one of my pfsense box with this modem on my remote site where 4g is the only last viable net solution..Will the modem will automatically get a new dchp address when ISP renew its address??

bradtpt · Aug 1, 2019, 8:57 AM

@jly2680 unfortunately no.

On other client sites I've used a netgear nighthawk in bridge mode for this and it's a solid solution... although for that to work you need to make pfsense override the subnet mask the dhcp passthrough from the nighthawk issues, it issues a /32 and needs to be changed to a /24 otherwise it can't contact the default gateway to actually get traffic out. To do this you need to add "supersede subnet-mask 255.255.255.0" to the "DHCP Option Modifiers" under the "Lease Requirements and Requests" portion of your interface connected to the nighthawk.

i got my e3372 and switch its firmware to stick mode..but my pfsense is based on 2.3.5 running on alix 2d13..I check the dmesg when I put my modem:

ugen1.2: <HUAWEIMOBILE> at usbus1 (disconnected)
u3g0: at uhub1, port 1, addr 2 (disconnected)
ugen1.2: <HUAWEIMOBILE> at usbus1
u3g0: <HUAWEIMOBILE HUAWEIMOBILE, class 0/0, rev 2.10/1.02, addr 2> on usbus1
u3g0: Found 2 ports.

no ue0 device at /dev .. doesnt show the NCM interface..Can I load the NCM driver using 2.3.5??

stephenw10 · Aug 7, 2019, 6:28 PM

Check the USB config output to see if it actually presents as an Ethernet interface there.

Looks like u3g found ppp interfaces though, you can probably connect that way.

Looks promising. Can you test it on something 64bit?

Or boot FreeBSD 11.3 on the ALIX maybe?

You might get it working in 2.3.5 with the right FreeBSD 10 kernel module. Really you should upgrade though. 2.3.X is unmaintained and should be considered insecure as a result.

I would prefer loading kernel module on 2.3.5,, but I dont have any links to dowload modules

Get them from the corresponding FreeBSD iso. 10.3 in this case.

I did try it on vmware lastest pfsense , NCM and ue0 interface showed..can you guide which module are needed to load on 2.3.5??

But when I load Freebsd 10.3 also on vmware,,no ncm and ue0 int showed,,

That doesn't bode well. It's probably just not supported there then.

You can use kldstat to see what kernel modules are being used.

Yes you can, you need to use the setport command from the AT command set for the modem to enable the NCM interface. I have another post with some details thrown in contained here: https://forum.netgate.com/topic/137637/huawei-e3372-will-not-reconnect-ppp-after-manual-disconnect-under-status-interfaces

In summary what you need to do is jump into the console and talk directly to the modem via the emulated serial port by running: cu -l /dev/cuaU0.0 or cu -l /dev/cuaU0.1 depending on which port it created and wants to talk on. Once in there run the command AT^SETPORT="FF;10,12,16" and then AT^RESET to reboot the stick. After having done this once, from herein the stick should present the NCM interface which is defined by the 16 in the command above.

PS - I can confirm this works on 2.3.x as I had a client on that version a while ago and utilized ones of these.

AT^SETPORT?

Unfortunately I don't have one with me to check the config directly, however have you modeswitched the device out of mass storage mode? If not, you'll need to download and install usbmodeswitch by running this (from memory 2.3.x is on FreeBSD10 so this should be the correct version):
pkg add http://pkg.freebsd.org/FreeBSD:10:amd64/release_4/All/usb_modeswitch-2.5.0.txz
and then running this:
/usr/local/sbin/usb_modeswitch -J -v0x12d1 -p0x1f01

Running that will cause the device to drop out of mass storage mode and should present the interfaces. Let us know how you go. If I had a stick with me I'd go through the motions and post it up for you but unfortunately I can only go off some notes I have here from the last one I did quite a while back.

The error from usbmodeswitch makes sense now I think about it, you have the stick firmware loaded so as such the device when inserted won't present as a mass storage device. I have an e3372 with the stick firmware loaded at work, if I get a chance tomorrow I'll fire up a machine with 2.3.5 and see if I can make it work. As I'm not familiar with your Alix hardware the closest I can go to replicating your environment would be to install an archived version of pfSense-CE-memstick-2.3.3-RELEASE-amd64.img I have here on an amd machine. Is your alix similar or a totally different platform?

Ahh ok, unfortunately netgate don't leave old versions online, I'll have to go digging and see if I can find a i386 installer kicking around somewhere. If you have a link or can dropbox it to me or similar let me know.
-edit- I just found this: https://mirrors.xmission.com/pfsense/downloads/pfSense-CE-2.3.5-RELEASE-i386.iso.gz and this: https://mirrors.xmission.com/pfsense/downloads/pfSense-CE-memstick-2.3.5-RELEASE-i386.img.gz so it looks like we're in luck.

I would be surprised if there's any difference between the 32bit and 64bit versions as far as this modem is concerned. The available tools should be identical.
