      Correct. I'm able to establish a connection using PPP and it works using the config I posted. The config was found on a FreeBSD forum for this specific LTE card. The set ifaddr line is a default from FreeBSD's /etc/ppp/ppp.conf as far as I am aware which enables the provider to set the IP upon connection.

      If the IP address changes whenever a connection is made, change this line to the following value. This tells ppp(8) to use the IP Configuration Protocol (IPCP) to negotiate a dynamic IP address:

set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.255 0.0.0.0

      I'm no expert in FreeBSD obviously. Can you see what I would need to do within pfSense to get this working with the information I have provided?

        Those values in mpd_wan.conf are set by the pfSense GUI. I did not see an option to select anything regarding IP addressing in the GUI.

          My own connection here also uses that config line but it does come up with that gateway:

          ppp0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
	description: 3GWAN
	inet6 fe80::208:a2ff:fe0c:bba%ppp0 prefixlen 64 scopeid 0x10
	inet 188.29.x.xxx --> 10.64.64.0 netmask 0xffffffff
	nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

          When you use your custom ppp file what IP does it actually come up as?

            You can use an entirely custom mpd conf file by creating: /conf/mpd_wan.conf.

            pfSense will use that in preference to the auto created file in /var.

                  Ok, so maybe try creating the custom file in /conf and setting the remote address to 10.0.0.2/0 there.
                  Both are /0 so it should allow any IP from either but it's a difference....

                    Same result. About to order a Mofi4500 and just use the pfSense strictly as a firewall at this point. It shouldn't be this difficult to configure an LTE modem. Especially one that is on the "Supported 3g/4g Modem" list.

                      I certainly wouldn't expect it to be given the right settings.

                      You will likely get better throughput from an external modem anyway though.

                        Hi, I'm using the MC7354 module but I can't figure it out how to solve this, can you guys help me out?

                        Do I need to reflash the module?

                          @canhtuongvinh said in Sierra MC7354 LTE for WAN:

                          The port you're using is not configured as an AT interface. Try one of the other ports.

                          But please keep this in one thread. It might be better to start a new thread than these older ones.
