Understanding How NAT Works: This section describes the functionality of Network Address Translation (NAT), its benefits, and required information for implementing address translation on a Cisco ASA.
Enforcing NAT: This section describes the difference between enabling NAT and requiring NAT on a Cisco ASA.
Address Translation Deployment Options: This section describes the many various forms of address translation on a Cisco ASA, gives examples of NAT vs. Port Address Translation (PAT), and describes which form of address translation is appropriate for various network scenarios, and in what situations NAT or PAT should not be used.
Configuring NAT Control: This section demonstrates how to configure NAT control, to require all transit traffic to be addressed by translation rules (and exemptions).
Configuring Dynamic Inside NAT: This section demonstrates how to configure dynamic inside NAT, create global address pools, and alter the default system translation slot idle timer value.
Configuring Dynamic Inside PAT: This section demonstrates how to configure dynamic inside PAT, allowing multiple internal hosts to share a single global IP address.
Configuring Dynamic Inside Policy NAT: This section demonstrates how to configure dynamic inside policy NAT, to create conditional translation rules based on the contents of access control lists.
Verifying Dynamic Inside NAT and PAT: This section shows commands used to verify NAT and PAT configuration on an ASA using dynamic inside NAT or PAT.
Configuring Static Inside NAT: This section demonstrates how to configure static inside NAT, to create permanent mappings between internal hosts and global IP addresses.
Configuring Network Static Inside NAT: This section demonstrates how to configure network static inside NAT, which allows for the creation of multiple static mappings with a single command.
Configuring Static Inside PAT: This section demonstrates how to configure static inside PAT, which allows multiple servers, using unique ports, to share a single global IP address. Static inside PAT can also be used to perform port redirection for servers using custom ports (where the port the connection is directed to by the client, and the port the server is actually listening on, are different).
Configuring Static Inside Policy NAT: This section demonstrates how to configure static inside policy NAT, to create conditional translation rules based on the contents of access control lists, for servers requiring only outbound connectivity.
Verifying Static Inside NAT and PAT: This section shows commands used to verify NAT and PAT configuration on an ASA using static inside NAT or PAT.
Configuring No-Translation Rules: This section demonstrates how to configure dynamic and static identity NAT, or NAT bypass, for hosts that do not require translation.
NAT Rule Priority with NAT Control Enabled: This section discusses the priority in which address translation rules are applied to traffic.
Configuring Outside NAT: This section discusses and demonstrates how to configure outside NAT, for use when external hosts require translation when communicating with hosts on more secure interfaces.
Other NAT Considerations: This section discusses effects of NAT on other elements of ASA configuration, and demonstrates how to configure DNS Rewrite.
Troubleshooting Address Translation: This section discusses steps in troubleshooting address translation issues.
