Remote Configuration Interface, Gateway IP Address
If Static IP is set as the Connection Type of the WAN interface, then this parameter configures
the gateway IP address for the SM for RF management traffic.
RECOMMENDATION:
Note or print the IP settings from this page. Ensure that you can readily associate
these IP settings both with the module and with the other data that you store
about the module.
NAT Protocol Parameters, ARP Cache Timeout
If a router upstream has an ARP cache of longer duration (as some use 30 minutes), enter a value
of longer duration than the router ARP cache. The default value of this field is 20 minutes.
NAT Protocol Parameters, 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. The default value of this parameter is 120 minutes.
NAT Protocol Parameters, 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.
The NAT tab also contains the following buttons.
Save Changes
When you click this button, any changes that you made on all tabs are recorded in flash memory.
However, these changes do not apply until the next reboot of the module.
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.
An example of the IP tab in an SM with NAT enabled is displayed in Figure 90.
