- NAT Refresh Interval
Interval between NAT refresh packets sent on a DTLS or TLS WAN tunnel connection. These packets are sent to maintain the UDP packet streams that traverse a NAT between the device and the Internet or other public network. You might want to increase the interval on interfaces where you are charged for bandwidth, such as LTE interfaces.
Range: 1 through 60 seconds
Default: 5 seconds
Change the NAT refresh interval to 30 seconds:
