If I understand:
When applying access list to interfaces, we apply the standard access list at the destination interface
we apply the extended access list at source interface or may be both.
Router(config-if)# ip access-group AccessListName out
My question is:
- if we have 2 routers routerA and RouterB both have 3 interfaces, but dierectly connected through one interface.
we need to apply an access lists to block SMTP traffic from router A to routerB
an we need to block all traffic from host 192.168.1.45 located behind routerB network and going to routerA
how can we configure access lists?
