<![CDATA[Are 4G modules inside firewalls compatible with pfSense?]]>Hello

Im looking at these firewalls which have great reviews online even though they are from weird no name brands and take 30+ days to arrive but come at good price and have good performance.

There is a option to include a "4G module" for them. Im interested because I currently have a 4G router hooked to a virtual pfSense and I do a DMZ host and thats how I have a backup but to have it all in the same device and correctly have two WANs would be much better.

Obviously it is not supported by pfSense in any way shape or form, but are they compatible and does pfSense see them? Can they be used?

Thanks

pfSense CE 2.6 / pfSense CE 23.01
Seirra Wireless MC7700 4G/LTE
Sierra Wireless MC7710 4G/LTE
Sierra Wireless MC7455 4G/LTE

So they are picked up by pfSense and can be used as a WAN interface? Intresting... Didnt expect it.

Yes you can use them then as an WAN interface let us say.
pfSense CE 2.6 / pfSense CE 23.01
Seirra Wireless MC7700 4G/LTE - miniPCie (full length)
Sierra Wireless MC7710 4G/LTE - miniPCie (full length)
Sierra Wireless MC7455 4G/LTE - M.2 (half length)

Install the modem, install the cellular package, find out the ugen number of your modem, find then out the right cuaU port, probe that port in console, create then an interface, and set up in the interface area mobile ISP, name
and password an so on. Then create if needed a Gatewaygroup and balance over that the enitre traffic
or let the modem only the fallback option, or perhaps
the only one WAN port. Like you need it.

And you must have a modem that is recognised and creates virtual com ports.
