Configure four types of NAT on the firewall (ASA)

The principle and router-based configuration of Network address Translation (NAT) have been introduced. The NAT configuration on ASA needs to be copied relative to the router. NAT on ASA has dynamic NAT, dynamic PAT, static NAT, static PAT. The link below is the N that I wrote before.

Fault handling of NAT

NAT failures are often encountered in practical work, which can basically be classified into two categories, namely, misconfiguration and failure to correctly understand the way NAT works. The symptoms of these problems are basically the same, that is, the IP address of the internal LAN is configured with NAT, while the internal
