Configuration Examples for 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 the NAT Function

This section provides an example for configuring the NAT function to implement multiple-to-multiple 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 Syslog Source Tracing for NAT Flexible Flows

This section provides an example for configuring syslog source tracing for flexible NAT flows. The log function can be used to record information about intranet users' access to external networks in real time, improving network maintainability. A networking diagram is provided to help you understand the configuration procedure.

Example for Configuring the Internal Server Through 1:1 NAT (Traffic Diversion on an Inbound Interface)

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.

Example for Configuring Bidirectional NAT

This section provides an example for configuring bidirectional NAT on an enterprise network. This function protects data within the enterprise network and translates both the source and destination, without exposing internal server data. A configuration networking diagram is provided to help you understand the configuration procedure.

Example for Configuring Static NAT Source Tracing

This section provides an example for configuring static NAT source tracing to implement many-to-one translation between private and public addresses and allow PCs only on a specified network segment to access the Internet.

Example for Configuring Outbound NAT Traffic Diversion, 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 IPoEoVLAN Access Together with NAT

This section provides an example for configuring IPoEoVLAN access together with NAT so that home users can access the Internet through NAT processing.
