Allowing ICMP

Sat Feb 18, 2023 12:49 pm

There are forum posts on here saying you should allow ICMP. I understand the reasons but wanted to ask a question.

My question
For traffic originating behind the firewall, and being NAT'd through the Mikrotik, do I need to explicitely create allow rules for ICMP on the input and/or forward chains when I already have the "established,related,untracked" rule?
