Table 1: Fields on the Add Source NAT Pool Page

Field

Description

Pool Name

Enter a source NAT pool name.

Pool Description

Enter a description for the source NAT pool.

Routing Instance

Select a routing instance from the list.

Pool Address Family

Select a source NAT pool IPv4 or IPv6 address family.

Pool Addresses

Enter the source NAT pool address range in the From and To text boxes. Click + to add the addresses.

To delete any addresses, select the address you want to delete and click X.

Port Translation

Select a port translation option from the list:

  • No Translation

  • Translation with Default Port Range (1024–65535)

  • Translation with Specified Port Range—Enter a port range from low to high.

  • Translation with Port Overloading Factor—Enter a value for the port overloading capacity for the source NAT interface.

Address Assignment

Select an option:

  • Enable Address Shared—Specifies that multiple internal IP addresses can be mapped to the same external IP address. Use this option only when the source NAT pool is configured with no port translation.

    When a source NAT pool configured with no port translation has few external IP addresses available, or only one external IP address, the address shared option, with a many-to-one mapping, increases NAT resources and improves traffic.

  • Enable Address Pooling—Select an option:

    • paired—Allows address-pooling paired.

    • no-paired—Allow address-pooling no-paired.

Utilization Alarm

Upper Threshold

Enter an upper threshold percentage at which an SNMP trap is triggered.

Range: 50 through 100.

Lower Threshold

Enter a lower threshold percentage at which an SNMP trap is triggered.

Range: 40 through 100.

Note: This option can be set only if you configure the upper threshold value.
