Stateful ipv6 firewall

Mon Jan 04, 2021 6:10 am

Dear Colleagues,

I have created firewall rules for IPv6 based on recommendations in https://wiki.mikrotik.com/wiki/Manual:S ... our_Router.

The rules work fine (permit outgoing traffic and return traffic, block incoming traffic) but there is one thing I cannot understand (maybe because I have an ipfw and pf background). Where is the actual "allow" rule which creates states in the firewall? It's nowhere to be found in the recommended ruleset. In ipfw or pf, until you create an "allow" outgoing keep-state rule, no return traffic will be permitted.

Is is implicit and hidden somewhere?
