Subyoz · June 19, 2015, 9:47am

Hi. I have Latvian 4g (BITE) LTE modem, Ethernet internet connection and RB951Ui-2HnD.
Ethernet Inet is my primary connection, LTE modem will be reserv connection.

I did all configs for LTE : pluged USb modem, created Dhcp client for LTE interface and created nat rule (masquerade)
But coz i have many NAT rules for my ethernet connection i need to copy it for modem. And there is problem.

Modem have static ip address 85.14.138.140
Dhcp client gives me 192.168.8.100
local network is 192.168.2.1/24

standart NAt rules with dst nat did not work. Where im making errors ?

You need to change modem firmware to ppp mode, then configure ppp-client interface on mikrotik and you will have your public static ip on ppp-client interface.
