port-overloading-factor (Security Source NAT Pool)

Syntax

port-overloading-factor

Hierarchy Level

[edit security nat source pool source-pool-name port]

Description

Configures the port overloading capacity in source NAT. If the port-overloading-factor is set to x, each translated IP address will have x number of ports available.

Note:

The port-overloading-factor statement cannot be configured with port no-translation (source NAT pool without PAT).

Options

  • Range: 2 through 32

For example, If you set port-overloading-factor to 2 for a source pool with two IP addresses, each with the single port range of 1024 through 2047, the ports are multiplied by 2, increasing the port capacity for each from 1024 to 2048. If the configured port-overloading-factor setting exceeds the maximum port capacity of the pool, an error message is generated during the configuration commit.
