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.

o Bit per second: 115200

o Data bits: 8

o Parity: None

o Stop bits: 1

o Flow control: None

On the CLI page, login to the SonicWall.

To Disable the Nat Policy, Enter the following commands:

· Configure

· Nat

· Show nat (to see policies and get number for the policy to disable/enable)

· Modify # (to modify policy 14 enter “modify 14”)

Just enabling or disabling the nat policy will not work, you have to make a change to it and then enable or disable it. For Example change the inbound-interface.

· Inbound-interface any

· No Enable disables NAT Policy

· End saves the changes and exits.

· Show nat verifies policy is disabled

To Enable the Nat Policy, edit the inbound-interface and then use the enable command.
