The line−by−line description of this display follows.

NAT functionality enabled (On/Off): On

This variable must be On (the current default value is Off) to allow the router to do Network Address Translation on any of its IP ports.

Note: Another NAT variable in the IP port must also be turned On for that port to perform Network Address Translations. This will be described in more detail later.

NAT Response to external ICMPs (On/Off): On

This variable must be On (the current default value) to allow any routers or workstations inside the NAT Network, behind the NAT Router, to respond to pings coming from outside the NAT Network. The router or workstation inside the NAT Network must have its address mapped to an address in the NAT External Range to allow the ICMP Echo Request packet through the NAT Router to the "private" IP address on the NAT Network.

Communicate w/ Router through IP Ports (On/Off): On

This variable must be On (the current default value) to allow the router to communicate through the addresses of its IP ports. This is part of Condition 2 described earlier and includes Telnet sessions and pings to the NAT Router.

Configured Ports: Ether0

This line lists the IP port which is currently doing Network Address Translation in the router.

Note: The NAT software is currently designed to allow only one IP port on a router to be doing Network Address Translation.

UDP timeout period (sec.): 300

The router will remove an active NAT Session for UDP (and all other non−TCP protocols) after 300 seconds (five minutes) if no IP sessions have used this NAT Session.

TCP timeout period (sec.): 86400

The router will remove an active NAT Session for TCP after 86400 seconds (24 hours) if no IP Network Address Translations have used this NAT Session.
