Access-List

If I applied an access list to deny Subnet A from accessing Subnet B, will it Subsequently results in that Subnet B can not access Subnet A ( this because when the reply packet returned from subnet A will be dropped by the access list).

If so how could I overcome this case? (i.e deny access from subnet A to subnet B and permit access from subnet B to subnet A?

a clarifying examples will be great.

Re: Access-List

you have to enable IOS Firewall on the router ( also known as CBAC ). Here is a link how to configure it
