You can delete a DNAT rule in a firewall template or on a CPE device. A DNAT rule deleted in a firewall template is automatically deleted on all CPE devices that use this firewall template.
Deleted DNAT rules cannot be restored.
To delete a DNAT rule:
Delete a DNAT rule in one of the following ways:
If you want to delete a DNAT rule in a firewall template, go to the SD-WAN → Firewall templates menu section, click the firewall template, and select the NAT → DNAT tab.
If you want to delete a DNAT rule on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the Firewall settings → NAT → DNAT tab, and select the Override check box.
A table of DNAT rules is displayed.
Click Delete next to the DNAT rule that you want to delete.
In the confirmation window, click Delete.
The DNAT rule is deleted and is no longer displayed in the table.
