NAT Access List Question

Unanswered Question
Aug 28th, 2007

Some of the examples I have seen of an access lists for NAT inside local addresses start with the first host in the range such as:

access-list 1 permit

I would think that the correct syntax would be the network address, not the host address, like this:

access-list permit

Am I wrong or right, or are both permissible?

I have this problem too.

You are right, and any way if you enter "access-list 1 permit" the router will automatically convert it to "access-list 1 permit", as the wildcard mask is telling the router which bits to match and which to ignore and the route will accommodate according to it.

Hi Oren,

For exams i'll say go for the standards by the book and use the "access-list 1 permit".

I hope that i've been informative.
