The best cisco router command in the world is...

Inbound Vs. Outbound

Is there any simplified explanation as to when setting access control lists on a Cisco router and to these two terms defined?
The sybex cisco book is somewhat confusing on these terms in their definition. And, on my CCNA test, i didnt have to worry about configuring these. On the MCNS, i would think so...well does anybody have a solid and clear definition of what an inbound access list (one would think going INTO the interface/router) vs outbound access list (going OUT OF the interface/router)? At least that is what i thought.

ACLs are per interface. So inbound traffic on e0 could be  going the opposite direction of inbound on s0. Something like this:

            e0                              s0
 --------|-----------------------|--------
-> is inbound on e0                 -> outbound on s0
outbound on e0 <-                 inbound on s0 <-

Hope this helps you.
