NAT Enable/Disable
Either disable NAT, or enable NAT to view additional options.
TCP Session Garbage Timeout
Where a large network exists behind the SM, you can set this parameter to lower than
the default value of 1440 minutes (24 hours). This action makes additional resources
available for greater traffic than the default value accommodates.
UDP Session Garbage Timeout
You may adjust this parameter in the range of 1 to 1440 minutes, based on network
performance. The default value of this parameter is 4 minutes.
Regardless of whether NAT is enabled, the NAT Configuration page also provides the
following buttons.
Save Changes
When you click this button, any changes that you made on the NAT Configuration page
are recorded in flash memory. However, these changes do not apply until the next reboot
of the module.
Undo Saved Changes
When you click this button, any changes that you made but were not committed by a
reboot of the module are undone.
Set to Factory Defaults
When you click this button, all configurable parameters on all configurable pages are
reset to the factory settings.
Reboot
When you click this button
1. the module reboots.
2. any changes that you saved by a click of the Save Changes button are
implemented.
Whenever you change a parameter in the NAT Configuration page, the system highlights
the Reboot button as a reminder that a reboot (in addition to a save) is required to
implement the changes.
18.2.5 Advanced Network Configuration Page of the SM with NAT Disabled
An example of the SM Advanced Network Configuration page when NAT (network
address translation) is disabled is shown in Figure 84. The default state of this page is
with NAT disabled.
