I want to harden my internet router.
Any link on this.
I cheked few links and find out that RFC 1918,3380 address to be blocked on externla int.
There is one entry like
access-list 101 deny ip host 0.0.0.0 any
access-list 101 deny ip host 255.255.255.255.any.
What is this host in the command.My internet router or something else.What should I use here..
And how these acl will work?
