<![CDATA[trying to add GSM dongle for WAN]]>Hi I'm trying to add a Huawei E3372-325 dongle to a 4200. Everytimne i try to add it. I lose access to the webgui and the console crashes. I saw the following error when I added the interface

trying to add GSM dongle for WAN.

arprequest_internal: cannot find matching address
arprequest_internal: cannot find matching address
arprequest_internal: cannot find matching address
arprequest_intern

any help trying to get this to work is much appreciated.
it seems to be a router dongle in some way as with I configure the interface to DHCP I get an ip of 192.168.8.100

You are better off with an external modem that connects via Ethernet. Makes it completely transparent to pfSense.

LM1200

$40 from Netgear, $25 from Amazon

I have the older LB2120 connected to pfSense for dual WAN failover.

But I came across this

Huawei E3372s LTE USB-stick
Link interface: /dev/cuaU0.1
Init string: &F&C1&D2E0S0=0

And this

Modems reported to work as Ethernet devices
Huawei E3372-325
