I am aware how CBAC does work , please look at the figure below (step 2) :
In step 2, he says: " CBAC creates a dynamic ACL allowing return traffic back through the firewall "
Does he mean by: " CBAC creates a dynamic ACL,,,,etc ", the command line underneath it ? :
Access-list 102 permit TCP host 172.30.1.50 eq 23 host 10.0.0.3 eq 2447
