i had a written test on this, it wasnt for CCNA but was in a revision exam for the CCNA
i was told to block all IP traffic to the internet from a network and explain how this could be done, i typed the following ACL's, I have just listed the deny parts of the list i wrote.
access-list 100 deny ip 192.168.0.1 any any eq 80
would that work?
I also wrote this one as another example
access-list 100 deny ip 192.168.0.1 0.0.0.0 eq 80 //denying the default route?
and finally this one
access-list 100 deny ip 192.168.0.1 172.16.0.1 eq 80 //deny access from192.168.0.1 to 172.16.0.1 on port 80
I forgot subnet masks/wildcard masks, does this matter or will the router automatically assign default where the subnet/wildcard is not assigned, I was just curious
