I have not worked much with extended ACL's so I'm confused about something. When I apply my extended ACL to a workstation access port on the 3750 it looks like this:

ip access-group <extended access group name> in

There is no "out" option in the setup. I don't understand why there is a directional option at all but I can't apply the extended access group unless I choose "in".

Obviously I'm missing something. Will the "in" option prevent traffic from traveling freely in both directions ???
