The Interface table is a dialog where WinRoute displays all interfaces available in the computer that it could recognize. If you should have more interfaces than WinRoute displays it is likely that the driver for such interface(s) were not properly loaded by the operating system and WinRoute could not read it.
You can see:
Name of the Interface
You can change the name by selecting “properties” and changing the name.
The value set in TCP/IP properties of the Interface. If the interface is set to get IP address from DHCP server you would see the actual IP address assigned to the Interface.
NAT “On” or “Off”
If NAT is to be performed on an interface then “On” is displayed in this column.
