5.6.3.1 NAT
On this WBM page, you specify the basic settings for NAT.
Description
The page contains the following boxes:
● NAT
Enable or disable NAT/NAPT for the entire device. When enabled, the device operates as
a NAT router.
● Idle Timeout [s]
Enter the required time. The device checks cyclically after the set period has elapsed
whether the aging time of TCP and UDP connections has elapsed. The connections whose
aging time has elapsed since the last check are deleted from the table "NAT Translations".
● TCP Timeout [s]
Enter the required aging time for TCP connections. TCP connections are stored until no
data exchange has taken place for the set period. Depending on the cyclic check when the
Idle Timeout has elapsed, the connections are deleted from the table "NAT translations".
● UDP Timeout [s]
Enter the required aging time for UDP connections. UDP connections are stored until no
data exchange has taken place for the set period. Depending on the cyclic check when the
Idle Timeout has elapsed, the connections are deleted from the table "NAT translations".
