Does NAT 0 require an access-list

Hi there,

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.

Thanks in advance for any replies.

Regards

CP

Re: Does NAT 0 require an access-list

For NAT 0, you dont have to have an ACL configured. If your IPs are routable, simply configure NAT 0 with that subnet and netmask.

Hope this helps.
