I am reviewing one of the Cisco ASA configurations and not able to understand the 2nd line with ACL:
access-list ABC extended permit tcp any host P.Q.R.S eq www // access-list DEF extended permit tcp host P.Q.R.S eq www any
My question is:
I am not using here NAT for the IP P.Q.R.S, also there is no need of reverse route for service www, as it will maintain the state, then whey they have allowed traffic from source port www?
It is mistake, or if it is right, why it is needed?
