When Cisco routers are routed first, when Nat first may be known, inside is routed first, outside is first Nat.Well, for Cisco ASA, it is not the case, most of the first to find the route if the data from inside, in both cases Nat will first route to confirm the interface. Did the purpose NAT conversion Static NAT session exists Once you know this feature, let's look at the following two cases CISCO
