R2(config)#access-list 1 permit 192.168.12.0 0.0.0.255 This single permit entry will be enough. At the bottom of the access-list is a “deny any”. We don’t see it, but it’s there. Let’s apply this access-list inbound on R2: R2(config)#interface fastEthernet 0/0R2(config-if...
The ‘any’ statement is there so as to allow traffic towards any IP destination on port 80. The first network statement in the access-list command (i.e 92.128.2.0 0.0.0.255) refers to the source of the traffic, and the second network statement (the keyword “any” in our example) ref...
