One To One
The One-to-One Network Address Translation (NAT) remaps one public interface IP address space into
another private interface IP address space and vice versa by modifying the IP network address information
in IP datagram packet headers.
The NAT function is only available in Advanced Gateway Router Mode (AGRM) or Advanced Router Mode
(ARM).
The current implementation of One-to-One NAT supports network configurations supported in AGRM / ARM
mode, such as AGRM / ARM-Bridge, Bridge-AGRM / ARM and Bridge-Mix [AGRM / ARM and Bridge] i.e. other
network configuration options are not supported by NAT, such as AGRM / ARM-AGRM / ARM network). For
more detailed information about NAT see section ‘Network Address Translation (NAT) Router’ on page 45.

Session Idle Timeout
This time defines the NAT session period in the NAT session table. The session will be automatically removed

table when a matching packet hits the NAT rule.
