Trying to setup the routerboard tonwork with an LTE connection as my WAN/ISP and use the single Ethernet port to pass traffic over Ethernet/LAN while allowing dhcp on LAN. I also need to manage ttl settings on the traffic heading out to the WAN/LTE interface. Help would be much appreciated. I have been able to get the LTE connection set up and it is registered and appears to be working. However, while I can ping google from the routerboard, i cannot ping anything from the Ethernet lan connection.
Please use more ENTER and “,” in your sentence.
What LTE module you used in RBM11G ?
You can ping a 1.1.1.1 from MikroTik itself ?
You can ping a mikrotik.com from MikroTik itself ?
You are sure that you have proper one APN for your ISP ?
You read a documentation for LTE and TTL ? Here https://wiki.mikrotik.com/wiki/Manual:Interface/LTE#Avoiding_tethering_speed_throttling

Thank you for responding. Yes, I can ping 1.1.1.1 or 8.8.8.8 from the terminal interface in RBM11G. I am using a Telit LM960A18 LTE modem. I am sure that I have the proper APN, and it was even showing as registered on the appropriate carrier network. The firmware version on the Mikrotik is 7.1.3 stable. I used the LTE quick set option for set up.
It appears as though I am connected to the cellular network, since I can ping outside addresses like 8.8.8.8. However, I am unable to get that connectivity through to the ethernet interface. I would like for the mikrotik to be able to run dhcp for the ethernet LAN network.
I have not read much about the info in the link you posted but will go do so and come back with any questions about that. Thank you again for the help.
This is basic stuff who is build-in feature, IP > DHCP Server..
At LAN network you can assign a IP who will be working as gateway for your LAN devices. When they use your IP as gateway then it’s done for routing. They can use DNS from any remote services like 1.1.1.1 etc.
You must do a IP Firewall Nat a new rule with masquarade action, typical SNAT chain.
You say you use a QuickSet, then you should have this done too.

About Telit, you can found some tips here http://forum.mikrotik.com/t/telit-lm940-how-to-get-working/127619/1
One additional note, the Telit 960s support both ECM and MBIM mode. On V7, you’d want MBIM mode. ECM mode will create a NAT network in-between. Maybe not the exact issue, but better if the Mikrotik get the IP directly from the LTE network - this requires MBIM mode (& V7 for MBIM). To check this, use:
/interface lte at-chat [find] input="AT#USBCFG?
with 2 = MBIM, 1 = ECM. Also, v7.2rc4 has more “Telit support” than 7.1.3. Specifically the 7.2rcX line will show the carrier aggregation data and RSRP and RSRQ, in MBIM mode, instead of just RSSI. To switch to MBIM you can use:
/interface lte at-chat [find] input="AT#USBCFG=2
It will reboot the modem, so it takes a minute to come back. You may also need to reboot RouterOS for it to pick up the new port configuration for MBIM.
