Figure 88: NAT Configuration screen, NAT without DHCP
When NAT (network address translation) is enabled, you may set the following NAT
Configuration page 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 seconds.
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 value 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.
