I have telit LM960 modem. With special APN name, I should get public IP from operator. But it doesn’t.
However, AT command to read PDP parameters, shows modem get IP as expected, but LTE interface, shows 192.168.225.11… address. Connection works, I can use internet.
When I change APN to standard one., LTE gets private range IP address.
CGCONTRDP: 1,5,data,"178.183.XX.YY",“213.158.199.1”,“213.158.199.5”
CGCONTRDP: 1,5,internet,“100.89.76.105”,“213.158.199.1”,“213.158.199.5”
In both cases internet works. Tracerroute goes thru 192.168.225.1.
Checked on ROS 6.47 and 7 beta. Same result.
Modem via USB in PC gets proper IP.
Different modem (huawei) with same SIM card in same mikrotik, interface gets proper IP.
This is normal in ECM mode.
MikroTik as vendor of his own modules create his RTOS who give that PublicIP directly to lte1 - but this is why that modem works only with MikroTik RB in ECM mode!
I have information from Telit US that DMZ and Any Freq/Cell Lock cannot be done at LM940/960 and any new features can be done for LM960A18… I hope that you have exacly that one.
About your problem. Solution is only to use MBIM mode and ROS7beta8 - only at that config this will be work.
AT#USBCFG=2 ← usb vendor-id=1041 | MBIM mode
Note: ros7beta6 works with mbim and telit lm940/960 but you can have problems with APN and reboot in loop and at-chat not work with Telit.
CGMM returns just LM960. Dont need Cell lock. Have only one in around ;-)Freq lock seems to be fine. I can set 1 to 4 bands via BND at command and use specific one, or up to 4 aggregated. Enough for me
Just figured out MBIM mode and beta ROS beta 8. Works fine. I hope ROS 7 stable is coming soon.
Edit: I was too fast. After restart, lte was connecting for 30 minutes, and as you wrote, some AT commands does not work anymore. It’s beta, so I should not complain.
Any idea, if in ECM mode, all incoming traffic to WAN public adress can be “redirected” to LAN side? Bridge mode, aka DNAT etc. On the model itself?
I’m giving up with mikrotik as LTE CPE with LM960.
I plugged LM960 via USB adapter into ubuntu machine (USBCFG=2, means MBIM). System asked me for APN and network name (it’s even knew all polish networks). And it works. Out of the box. Connects on data APN, gets proper IP, no extra efforts. Just like this. Will find some embedded 6W NUC/SBC MB with low TDP processor and … sorry mikrotik.
It’s CPE. Need iptables, VPN server and 2 ports forward. No rocket science in linux.
Use ROS8beta8 - at-chat works. Remember before some character you must add \ like to write " you do ".
You reach a problem with disconnection in look and connection no longer then 1h… I see this too and report to MikroTik, in progress.
Yes, It’s beta and that way it’s should be used at production.

This is Telit feature… to not give a www panel at 192.168.225.1 at what you can just click to set PortForward/DMZ.
Hi SiB, I jump onto this subject as I have exactly same issue as Marcin.
Using EP06 in Wap-R-ac, LTE1 shows 192.168.225.40 while the real public IP is 37.xxx…
I am on 6.46. (as 6.47 has that that disk write cycle problem and R7 is nothing for me yet…)
I believe I saw the real public IP address before in older ROS version (but might be wrong).
The funny thing is, all my clients do work fine over this device (I use it as FWA, an outside 4G modem connected to inhome Audience).
The real issue is, when I run trace route to example 8.8.8.8 from that router (or to any other server) it does not work (it drops at 192.168.255…) . Same for netwatch, it does not work
connection is always “down”…
The device is installed outside and I want to use Netwatch to reset/reboot the device in case of connection problems. From time to time it
has some errors (like SIM card no more detected, or LTE connection gone).
Any hint what the problem might be, or what the solution could be?
This is normal for all vendors in ECM mode.
Quectel give you a www panel, try open in browser 192.168.225.1 to open interface to set settings at EP06 itself… but be aware that DMZ feature not work and this is place where you should assign: “[EC25-AU] Web interface and DMZ in ECM mode”
You can try that at EP06 and if webpanel not open or this DMZ function not work then…
a) upgrade fw of EP06-E to EP06ELAR04A03M4G (v4.03) but if you have EP06-A then sorry, I not know if this is the same package. Try reach your FEA from support@quectel.com for proper QFlash + FW.
b) create a dedicated post at Quectel forum in LTE-A subcategory.
I believe I saw the real public IP address before in older ROS version (but might be wrong).
ROS6 it’s possible only at PPP mode with PPP-out1 at usb1 device… this is default for new device.
To grab speed and PublicIP properly we must use ros7b8 and mbim mode.

Differ fw at ECM mode works differ way. General is to block tracerout… but pings should works fine and the NetWatch should be usefull in ECM mode too. SAA1#MeWorks
From time to time it has some errors (like SIM card no more detected
I not support any of that ceses, I know that @dad232 have that experience and he count all cases at forum with broke sim slog port… but to be this problem as software… sorry but I not have that, only I read old post about this problems. You can watchdog that stuff by LteLogger2 and with litle modify you can detect and triger your fix script.
Check: Watch LTE parameters: http://forum.mikrotik.com/t/sxt-lte-4g-cat6/134468/1
That stuff should be diagnose and fixed, I help with many that stuff.
Currently Telit LM940 do many diconnection with ros7b8 and with support we try fix this…
PS. I am Marcin and from Poland too
Best Regards
