- [Instructor] We're going to see NAT in action here, I hope,…with ACLs and of course, we're going to spend our time here…with dynamic NAT or DNAT…because static NATs, that one-to-one mapping…of inside/outside addresses really doesn't involve ACLs.…But boy, dynamic NAT sure does…and dynamic NAT is much more prevalent in today's networks,…so we've got to be ready to use our ACLs with that.…And a little bonus troubleshooting of the last lecture here…or sentence, I should say.…But let's get started.…ACLs, frankly, they're the first thing I check…when there's any issue with dynamic NAT.…
Might look at my inside and outside statements first.…It's a good place to start.…But with the ACLs, because what they're doing is…they are identifying the addresses or the hosts…that can draw a routable address from the NAT pool.…And what we're going to do in this lab…is translate the addresses 10.1.1.1…and 10.1.1.11, both /32s,…while performing no other translation.…And just for fun,…just for something a little bit different here,…
