Guys,
I have problems with my PCC configuration between 2 ADSL (both modems are in bridge mode) and 1 LTE (Huawei B 315 in normal mode).
Most of the time internet works fine, but apparently when the connection switches from the ADSL to the LTE the users lose the connection to the internet due to DNS problems. Altough DNS is set as Google in the Mikrotik.
Lines below my configuration:
/ip address

Anyone got any clue why this is happening? Any help would be very appreciated
