47.3 The SNAT Status Screen
The SNAT Status screen allows you to view and quickly link to specific source NAT (SNAT) settings.
Click a function box in the SNAT Flow section, the related SNAT rules (activated) will display in the
SNAT Table section. To access this screen, click Maintenance > Packet Flow Explore > SNAT
Status.
The order of the SNAT flow may vary depending on whether you:
• select use default SNAT in the CONFIGURATION > Network > Interface > Trunk screen.
• use policy routes to control 1-1 NAT by using the policy control-virtual-server-rules
activate command.
Note: Once a packet matches the criteria of an SNAT rule, the ZyWALL/USG takes the
corresponding action and does not perform any further flow checking.
