NXC Series User’s Guide

CHAPTER 32
Packet Flow Explore
32.1 Overview
Use this to get a clear picture on how the NXC determines where to forward a packet and how to
change the source IP address of the packet according to your current settings. This function
provides you a summary of all your routing and SNAT settings and helps troubleshoot any related
problems.
32.1.1 What You Can Do in this Chapter
•The Routing Status screen (Section 32.2 on page 367) displays the overall routing flow and
each routing function’s settings.
•The SNAT Status screen (Section 32.3 on page 370) displays the overall source IP address
conversion (SNAT) flow and each SNAT function’s settings.
32.2 The Routing Status Screen
The Routing Status screen allows you to view the current routing flow and quickly link to specific
routing settings. Click a function box in the Routing Flow section, the related routes (activated)
will display in the Routing Table section. To access this screen, click Maintenance > Packet
Flow Explore.
The order of the routing flow may vary depending on whether you:
• select use policy route to override direct route in the CONFIGURATION > Network >
Routing > Policy Route 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 a routing rule, the NXC takes the
corresponding action and does not perform any further flow checking.
