Hi all
Need some help regarding ACL configuration.
Let's say I have an ASA with 4 interfaces (A, B, C and outside. Security levels for A,B,C are equal, outside is less)
All clients on networks A,B,C are allowed to connect to outside. In this case I don't need to configure an ACL as all traffic to less secure networks is allowed.
But what to do if I want to allow one host on interface A to connect to one host on interface B? Of course, I can add an ACE to interface' A inside ACL to allow that but will loose my implicit rule and connectivity to outside.
Is there a way to add an ACE on inside ACL for interface A allowing traffic that needs to go out of outside?
