the router do not tell anything, you have instructed it to log on one rule: log=yes log-prefix=“! public”
and as usual with the … we can not even check what is written after.


On that line you read only “code 3”?
Read all first, and study how ICMP works.

so how i can disable this log from appearing..? where is the controlling log center..?
i didn’t understand what you mean by this sentence “and as usual with the..we can not even..etc”

where are log=yes log-prefix=“! public” on your config?

where are the … on image?

sorry Mr rextended but it seems that i still didn't understand what you mean by that..! However, as you you see, this is all my firewall config -( in the attached file)-
and for more info i notice that when i disable all my firewall rules, this repeated message has gone, so my question what happen in my mikrotik to caue this message to appear in the log as you see in the picture..? i have this firewall rule for more than a month and no such thing appear in the log before.

I will try to explain as simple as I can.

Try learning what ICMP does, and how it works.
