RouterOS Beginner Basics

Ok, so I had this working then a setting caused me to hard reset. I have all my APN settings in and want to see what I am possibly missing here..

firewall rules - fast track disabled

mangle - pre routing IN. interface LTE1 (ive tried both having it selected and not) ttl - equal - 65 - action: change TTL - TTL action change - new TTL: 65 - not passthrough
mangle- post rouing out. interface all ethernet (tried both having it selected and not) ttl - equal - 65 - action: change TTL - TTL action change - new TTL: 65- not passthrough

the data is still getting reported and my ping ttl are not coming up… I feel like im missing something here. suggestions?

Does the LTE interface connects/works if you don’t modify the TTL in the firewall? I’d make sure the LTE interface is working cool - adjusting the TTL isn’t fix connection issues.

Assuming it otherwise works and you need to modify the TTL for some reason…I think you want to do this in “postrouting” chain for the “lte” interface not “ethernet” interface. You shouldn’t need to do anything inbound.
