I have two network adapters in Network Connections under the “LAN or High-Speed Internet” group and their numbering is the opposite of the one in the DynSite Setup > Connections tab, why?
This is by design, these figures do not have the same meaning. Windows assigns a name to each adapter and appends an optional number when there are multiple adapters. On the other hand, DynSite assigns a name to each interface and/or address, there may be multiple addresses per adapters. The numbers are assigned in the order the system enumerates the addresses.
