Configuring a 3g/4g USB modem on a Fortigate.

#config system modem
#set status enable

This should get the modem showing up in the GUI

#set phone1 *99#
#set extra-init1 “at+cgdcont=1,\”IP\”,\”broadband.windmobile.ca\””

If modem id needs to be added:

First get the USB device ID:

#fnsysctl cat /proc/bus/usb/devices

#config system 3g-modem custom
#set vendor “My Phone Company”
#set model “my phone model”
#set vendor-id “ff55″
#set product-is “88aa”
#end

Enable 4G/LTE:

#config system global
#set usb-lte enable
#end

Troubleshooting:

#diagnose sys modem detect wireless
#diagnose sys modem external-modem
