The command syntax format of a standard ACL is
access-list access-list-number {permit|deny} {host|source source-wildcard|any}
.
This is an example of the use of a standard ACL in order to block all traffic except that from source 10.1.1.x.
interface Ethernet0/0
ip address 10.1.1.1 255.255.255.0
ip access-group 1 in
access-list 1 permit 10.1.1.0 0.0.0.255
I have a question: If the Standard ACLs are applied on interfaces closer to the destination, I suppose they are always applied in the outbound direction. Am I wrong or in which situations can they be applied in the inbound direction?
