How do you decide if you apply an access list IN or OUT?
Take this diagram for example: http://mvpbaseball.cc/acl.jpg
If I wanted to deny the SALES lan from accessing FINANCE.
It would be
access-list deny 172.16.40.0 0.0.0.255
access-list permit any
I would then apply it to the e0 interface. But would I apply it inbound or outbound? How can you tell?
