If NAT is applied to communications between the Secure SD-WAN Engine and some other component that contacts the Secure SD-WAN Engine, define the Default contact address for the single Secure SD-WAN Engine or the Cluster Virtual IP Address (CVI). You can also define location-specific contact addresses.

	 Steps
- 
                Select  Configuration. Configuration.
-  
		  Right-click an engine element and select 
			 Edit <element type>. 
		   
		
-  
		  In the 
			 General pane, select the 
			 Location for this element. 
		   
		
-  
		  Browse to 
			 Interfaces in the navigation pane on the left. 
		   
		
-  
		  In the tree view, expand the tree and double-click the Cluster Virtual IP Address (CVI) or the IP address for which you want to define a contact address. 
		   
		  On Engine Clusters, the CVI contact address is used for VPNs and NDI contact addresses are used for other system communications.  
-  
		   In the 
			 IP Address Properties dialog box, define the Default contact address. The Default contact address is used by default whenever a component that belongs to another Location connects to this interface. 
		   
		   
			 - If the interface has a static Default contact address, enter the Default contact address in the 
				Default field. 
			 
- If the interface has a dynamic Default contact address, select 
				Dynamic (next to the 
				Default field) before entering the Default contact address. 
			 
 
-  
		  If components from some Locations cannot use the Default contact address to connect to the interface, click 
			 Exceptions to define Location-specific contact addresses. 
		   
		   
		
-  
		  Click 
			 Add and select the Location. 
		   
		
-  
		  Click the 
			 Contact Address column and enter the IP address that the components in this Location use when they contact the interface or select 
			 Dynamic if the interface has a dynamic contact address. 
		   
		   
			 Note: Elements that belong to the same Location element always use the primary IP address (defined in the element’s properties) when contacting each other. Elements that do not belong to a specific Location belong to the Default Location. 
			  
 
-  
		  Click 
			 OK to close the 
			 Exceptions dialog box. 
		   
		
-  
		  Click 
			 OK to close the 
			 IP Address Properties dialog box.
