I have similar problem - I have one more router behind my mikrotik router and it looks like my ISP started blocking traffic coming from behind that. I’d like to reset TTL on all the outgoing traffic.
How can it be done from the web interface of my router?
@xaocass
Open a terminal window in webfig and then copy paste:
/ip firewall mangle add action=change-ttl chain=postrouting new-ttl=set:64 out-interface=ether1 passthrough=no
assuming outgoing traffic passes through ether1 to your ISP. If not, change ether1 above to the correct interface.
