Configure NAT translation timeout values. ip nat translation {timeout | udp-timeout |

ftp-timeout} seconds
Clear dynamic NAT translations. clear ip nat translation
Clear a specific active simple NAT translation. clear ip nat translation inside global-ip local-ip

Note: For purposes of our examples we will not modify the maximum number of translation entries
or any NAT router limits. These parameters should only be modified to assure availability to
functionalities that share these resources such as TWCB and LSNAT. It is recommended that you
consult with Enterasys customer support before modifying these parameter values.
Depending upon the firmware version, the CLI prompts on your system may differ from those
presented in this section.
We will also assume that the FTP control port will use the default value.
