Configuration Examples in Typical Scenarios 01 - NAT
Example for Configuring Simplified NAT

This section provides an example for configuring the simplified NAT function to implement multiple-to-multiple IP address translation between private and public networks and allow PCs on a specified network segment to access the Internet.

Example for Configuring Both Centralized NAT and a Common IPsec Tunnel

This section provides an example for configuring both centralized NAT and a common IPsec tunnel. A NAT device converts private IP addresses to public IP addresses before sending packets to an IPsec tunnel established using a security policy.

Example for Configuring NAT Traffic Distribution on an Outbound Interface, Easy IP, and the Hairpin Function

This section provides an example for configuring NAT easy IP on an outbound interface and the hairpin function. The function combination allows internal hosts to access the Internet through the outbound NAT function and to access an internal server that is created using the easy IP function.

Example for Configuring the Centralized NAT Function (Distributed Scenario)

This section provides an example for configuring the centralized NAT function to implement many-to-many translations from internal addresses of enterprise users to external addresses and allow only PCs on a specified network segment to access the Internet.


Example for Configuring the Internal Server Through 1:1 NAT (Distributed Scenario)

This section provides an example for configuring the internal server through 1:1 NAT. By specifying an internal NAT server and configuring the mapping entries between the internal server's private IP address/port and public IP address/port, an external host can access the internal server
