I am trying to configure NAT 0 to allow my routable ip addresses to access the internet without requiring translation.
Do I need to specify an access-list to allow traffic originating from the inside to the outside.
I have got conflicting answers to te above question while referring 2 books from Cisco Press. While one mentions that an access-list is only required to allow traffic from the outside to the inside, the other mentions that an access-list would also be required to allow the inside routable addresses to access the outside network.
Can someone please clarify this for me as I am haven't been able to obtain a definitive answer.
