some of the verbs such as established sound familiar from the days i used to work with Cisco access lists and checkpoint firewall the new command wasn't known to me
The firewall filters in a MikroTik (and on Linux in general) are far more advanced than the simple access lists in a Cisco router. On a Cisco router you generally just have static rules that allow e.g. traffic incoming on some ports. (there are some exceptions, e.g. "reflexive" access lists)
