=== Problem Description 
There is a problem with XCP code for a static NAT configuration on a VCS-E
where only 1 NIC is used.
Static NAT is enabled by adding a multiple interface option key, which in turn
enables a second LAN in database.
As second LAN is marked as enabled, XCP logic will use this second LAN for
internal address (port 7400). 
A good  portion of the Customer base are using the "Advanced Networking" key
only for static NAT and they do not use the second NIC.
