Configuring Routed mode

Description

Routed Mode provides an alternative for NAT for routing traffic between separate public IP address ranges. Consider the following topology where the firewall is routing traffic across two public IP address ranges:

10.50.26.0/24
172.16.6.0/24

By enabling Routed Mode on the interface for the 172.16.6.0 network, NAT translations will be automatically disabled for the interface, and all inbound and outbound traffic will be routed to the WAN interface configured for the 10.50.26.0 network.

Resolution

Resolution for SonicOS 7.X

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.

To configure Routed Mode, perform the following steps:

Navigate to the Network | System | Interfaces page.
Click on the configure icon for the appropriate interface.
Click on the Advanced tab.
Under the Expert Mode Settings heading, select the Use Routed Mode - Add NAT Policy to prevent outbound\inbound translation checkbox to enable Routed Mode for the interface.
In the Set NAT Policy's outbound\inbound interface to pulldown menu, select the WAN interface that is to be used to route traffic for the interface.
Click OK.

The firewall then creates “no-NAT” policies for both the configured interface and the selected WAN interface. These policies override any more general Many-to-One NAT policies that may be configured for the interfaces.

Resolution for SonicOS 6.5

This release includes significant user interface changes and many new features that are different from the SonicOS 6.2 and earlier firmware. The below resolution is for customers using SonicOS 6.5 firmware.

To configure Routed Mode, perform the following steps:

Navigate to the Manage | Network | Interfaces page.
Click on the configure icon for the appropriate interface. The Edit Interface window opens.
Click on the Advanced tab.
Under the Expert Mode Settings heading, select the Use Routed Mode - Add NAT Policy to prevent outbound\inbound translation checkbox to enable Routed Mode for the interface.
In the Set NAT Policy's outbound\inbound interface to pulldown menu, select the WAN interface that is to be used to route traffic for the interface.
Click OK.

The firewall then creates “no-NAT” policies for both the configured interface and the selected WAN interface. These policies override any more general Many-to-One NAT policies that may be configured for the interfaces.

Resolution for SonicOS 6.2 and Below

The below resolution is for customers using SonicOS 6.2 and earlier firmware. For firewalls that are generation 6 and newer we suggest to upgrade to the latest general release of SonicOS 6.5 firmware.

To configure Routed Mode, perform the following steps:

Navigate to the Network | Interfaces page.
Click on the configure icon for the appropriate interface. The Edit Interface window opens.
Click on the Advanced tab.
Under the Expert Mode Settings heading, select the Use Routed Mode - Add NAT Policy to prevent outbound\inbound translation checkbox to enable Routed Mode for the interface.
