Dynamic NAT

Dynamic NAT translates the IP address of packets from one interface to another interface based on configured conditions. Dynamic NAT requires packets be switched through a NAT router to generate translations in the translation table.

To define a NAT configuration that can be applied to a profile:

  1. Select the Configuration tab from the Web UI

  2. Select Profiles from the Configuration tab.

  3. Select Manage Profiles from the Configuration > Profiles menu.

  4. Select Security.

  5. Select NAT.

  6. Select the Dynamic NAT tab.

  7. Refer to the following to determine whether a new Dynamic NAT configuration requires creation, edit or deletion:

    Source List ACL

    Lists an ACL name to define the packet selection criteria for the NAT configuration. NAT is applied only on packets which match a rule defined in the access list. These addresses (once translated) are not exposed to the outside world when the translation address is used to interact with the remote destination.

    Network

    Displays Inside or Outside NAT as the network direction for the dynamic NAT configuration.

    Interface

    Lists the VLAN (between 1 - 4094) used as the communication medium between the source and destination points within the NAT configuration.

    Overload Type

    Lists the Overload Type used with the listed IP ACL rule. Options include NAT Pool, One Global Address and Interface IP Address. Interface IP Address is the default setting.

    NAT Pool

    Displays the name of an existing NAT pool used with the dynamic NAT configuration.

    Overload IP

    Enables the use of one global address for numerous local addresses.

    ACL Precedence

    Lists the administrator assigned priority set for the listed source list ACL. The lower the value listed the higher the priority assigned to these ACL rules.

  8. Select Add to create a new Dynamic NAT configuration, Edit to modify an existing configuration or Delete to permanently remove a configuration.
