Re: access lists

Yes, one ACL can be applied to multiple interfaces.

Additional note, one incoming and outoing ACL per protocol can be applied to a interface.

Re: access lists

in the majority of cases do you normally have 1 list for in and 1 list for out ?

Re: access lists

Mostly put as 1 access-list per protocol per interface per direction.

so that mean 1 IP access-list in and out per interface, in the same case for IPX.

Re: access lists

so that would be say

int s0 ip access-group 101 in

int e0 ip access group 102 out

Re: access lists

Correct! You can also apply inbound and outbound ACLs to the same interface.

Interface Serial0

ip access-group 101 in

ip access-group 102 out

As stated earlier, one protocol per interface per direction. ACLs are fairly flexible and have multiple uses. How you implement ACL, determining the interface, protocol, and direction are all derived from system requirements.
